#Howviruseswork #microbiology #COVID19
It makes me sad to watch this and realize that if I had good teachers in school, I could have understood this stuff and maybe gone into a career in science or medicine. Dr. Seheult is truly an outstanding teacher, and I’m grateful for the time he spends to make these videos.
Yes! I understand how that feels like. I fall in love with biology because i had good teacher who opened my mind how interesting biology can be. I always wanted to pursue medical since then but end up in engineering due to scholarship. Now, I am currently in my 7th year of my 4 years electrical engineering degree. Hopefully, somewhere somehow in the future I able to work in medical industry with my engineering degree(hope such thing exist)
Just be happy our children will have it :)
money. this information has a cert (price) attached to it. they'll never teach anything in depth at school, it goes against their agenda. after a few of these vids im now a certified youtube doctor lol
I wish I had understood this long ago!
Mayby it´s never late to learn...
20 years ago it took me soooo long to understand DNA, RNA and Protein Synthesis. How simple it would have been if I'd had this video back then. Thank you!!
30yr for me true that
Good to hear, thanks!
@@MedcramI'm now using your channel to revise many different topics. Fantastic! So there's at least one good thing to have come from covid-19
@@loudieselj3165 I thought molecular biology not that long ago. 10 yrs the most like crypo-EM, those are very recent fields
@@friendsonearth I had micro biology in '95, so twenty five years ago.
I sit here and chuckle, as I received an "A' in my undergrad Cell Biology course, because I could memorize "information" and regurgitate it on examines. Problem was I had zero understanding at the beginning and end of the semester. These videos take me back to that class in the fall of 1973. Thanks for lifting the veil, now, as a retired dentist.
The struggle in understanding back then, hours of pouring over texts and in 12 minutes I understand enough of the picture to see where I have deficits.
Thank you Dr. Seheult.
Phi Ditto AMEN !!!!!!! :):):)
Egad. Dr. Seheult has so many things to do, now more than ever. And here he is educating me on "how viruses work a human cell." THANK YOU.
Most of what Seheult said was wrong, he failed to mention reverse transcription ( retroviruses ), splicing of introns from messenger RNA ( mRNA ) and ligation of remaining exons, alternative splicing, use of L amino acids rather than D, glycosylation ( sugar modification ) of proteins via protein trafficking. Cleavage of proteins such as pro-insulin into insulin. There are many different mechanisms that viruses have evolved with respect to viral replications for example Ribosomal frameshifting, etc. I am a Molecular Biologist. I recommend Eric Lander MIT lectures on fundamental Molecular Biology.
@@chroniclerofthe70s huh?
Nearly 50 years ago I sat in a classroom and learned a lot of this. How is it that nowadays I find it all so much more wondrous? I wish I’d made more of it back then.
Thank you so much for re-opening this subject for me and making it so fascinating.
Please note a correction at 7:01 As stated earlier in the video, RNA uses "U" rather than "T". I accidentally used "T" in my RNA example, sorry about that!

Hi friend. Brazil detected 1 positive case in a traveler from Italy. Case has been under control til now. Congratulations for the good informations in your Channel
MedCram - Medical Lectures Explained CLEARLY what is the best way to possibly send you information I’d like to request you looking over, giving your expert opinion on and maybe making a YT video addressing?
I've been enjoying this channel ever since you started doing the Coronavirus updates. Thank you for sharing your knowledge, concisely, with all of us who didn't do so well in science class lol.
Well it’s been 15 years since I covered this subject, can’t believe how much I still remembered!
Your teaching method is exemplary! Thanks for all the lectures & keeping my practice as a paramedic safe, informed and up to date!
Who knew there was so much going on in a living cell....thank God for the researchers and clinicians that spent their lives learning this science....
Spain: 2 students from a school in my city have been quarantined for being suspects of COVID-19, they have traveled to Germany in the past week. Scary tbh...
Dr. Seheult, thank you. That was terrific.
I have seen this process taughtmany times and you gave me a great new angle.
I am grateful for getting the opportunity to learn something.
Dr Seheult, it is good of you to expand your teaching to a wider non-medical audience in this way so I have finally subscribed. This was my Achilles Heel when studying for my A&P qualification so you will have my full attention during these lectures. Thanks again.
Just wanna give a shout out to my cells. I don't know how y'all do it. No really I don't. Frickin wizards.
@Ketu71491 - I liked your shout out :-) We are fearfully and wonderfully made by our creator: God.
@@newbeequilter If God would be involved in any way he would be the one who just killed 2500 innocent people with the corona virus... great guy.. really... clap clap
@@newbeequilter My creators are Mother and Father. No god was involved.
Ketu71491 Isn’t it amazing though? It took billions of years to evolve to be able To produce a cell that does this. It gives me great respect for the tiniest little plant or animal. Like us, made of cells.
And a shout out to all the brainiac Molecular Biochemistry Researchers who, over the years, have figured out how our cells work!
This was so helpful and surprisingly I could understand most of it despite not having taken Biology since high school. Thanks for the great easy to understand explanation!
Great refresher, Dr. Seheult! Thank you for taking time to make these videos :)
Yet another excellent video explaining something pretty complex in way almost anyone can understand. Thank you MedCram.
He just summed up 1 semester of immunology class back in the day when I was in med school...at the time it didn’t seem so simple or clear !!! :)
Excellent explanation. I'm an engineer but the way Dr. Seheult explained everything I had no problem understanding the process. Most people have an image of a virus as something that will annihilate them once they come in contact with them.
Thank You doctor for taking the time to share this knowledge with us regular people.
I have been studying this DNA, RNA,nucleotide, polypeptide,protein familar with the topic of RNA polymerase, m-rna but now I vividly understand after watching . I wish I had a good lectures who can let us understand genetics materials things easily like this. Thanks for this video. Worth watching 😊
Why didn’t we have such good teachers! This was such an informative video. Thank you
Your videos are so amazing! Such clear explanations..! I took psychology in college so I last studied biology only when I was at school and I could remember how difficult molecular biology would be at the school level itself. But such detailed overview being explained in such a simple manner is absolutely amazing! You are truly an inspiration for teachers to keep learning and developing!!
Great blast from my past. Amazing description of this!
This brought me back to day dreaming in high school and yes i started day dreaming again but you did a much better job than my science teachers
Excellent and simpler review of what I have learned in the university! Thanks for this.
I am not sure why I am watching this, I still remember this stuff from university, and I may remember still even some of the finer details that will not fit 10 minute video:) Anyway great video, I like your ability to explain clearly complex stuff and skip some less important details to focus on the important bits.
Thank you so much for the video!!
You made a complex concept so much easier to understand. YOUR confidence inspires my own confidence, which then makes learning so much easier.
I was following along and really understanding the process. Connecting some dots between terms tossed around and things I have learned previously. I was feeling, pretty pleased with my grasp of this complex process right up to when we went from transcription to translation. At that point the alphabet soup became more than my gray cells could hold at once. This is among the reasons I am not a molecular biologist but also the reason I keep watching videos like this. I want to understand just for the knowledge of how life works. So I will keep watching until the rest of the lights go on for me.
Thank you for making this video and putting it out to the general public.
When he said "DNA codes for the different types of proteins that are in the nucleus," did he mean in the "cell" rather than in the "nucleus"? I'm trying to understand this.
I felt like I understand something with the help of habitual reading on neuroscience. I also hope Dr. Roger Seheult can include why and how proteins get tangled. Thanks so much more power to this channel.
One comment I heard a while back helped me understand molecular biology a lot better, and it went something like this:
"These structures assemble themselves into the correct shape for their function"
I think this is a key and non-obvious point, that the behavior of proteins is as a direct result of their composition.
Wow, great video!
I used to work in genetics as a software developer and coming from a computer science background I knew nothing about genetics, so I tried to read up on and understand the basics.
Nothing I read made as much sense as this video has - so thank you for making this video.
Great to hear you found it helpful. Thank you for watching!
Love love love your podcasts. You got me through bio. And I absolutely love your podcasts re chloroquine and covid19. Now the world is listening 🙏🙏🙏
Haven't gone over any of this for 20 years lmao. Never thought I'd need Micro again.
Thank you for your clear explanation. I will pass this on to my students.
Easiest explanation of a very complicated subject. thank you
Great informative video as always. Thanks for posting.
Fantastic! Your videos are just awsome! Keep up the great work. Best wishes from your fan Norway :)
Awesome lecture. Thanks. Clears a lot of "theories" up.
Uneducated in this topic here... followed it perfectly fine and made a lot of sense.
Thank you
Amazing job thank you 🙏🏽 I still don’t all the way understand it but I definitely learned way more from this video!
I very prefer this than schooling! Thank you Doctor :)
Genius. Really good job explaining the complex concepts of molecular biology into a simple and concise explanation.
Thank you
Thank you for the review I loved studying medicine. You rekindled a passion.
You're amazing doctor! I really love your lectures like this on UA-cam!
Thanks for telling it to our level of understanding.
Hi! How do you make this black board neon writing discussion? What app or hardware did u use? I love your discussions btw! This is about the only update I trust and listen to on the coronavirus outbreak. Much appreciated!
You are to medical and biology education as Paul A. Foerster was to mathematics education for me. This is the best way to complement you as Mr Foerster is big in Texas mathematics teaching.
Thank you, I appreciate you sharing your knowledge with us.
Great explanation, even though that English is not my mother language, it was pretty clear and straight forward to understand. Thanks for the video and please keep doing them!
Your videos are life saving knowledge. Thank you.
This is very good review. My knowledge on molecular biology has been very rusty for so long.
Awesome work Doctor Seheult. Fabulous explanation.
Excellent video, explained with the perfect depth for understanding. Thank you so much. Subscribed!
Thanks for the feedback and sub!
The MedCram series provide great summaries. However, there is small glitch in this one. There is no thymine (T) in RNA, as mentioned earlier in the video the T in DNA is replaced by uracil (U) in RNA. This is true for all forms of RNA including mRNA, tRNA and rRNA. I often misspeak in the same way in lecture, but there I have a live audience to correct me.
Yes, sorry for accidentally using "T" in my example of RNA. I've added a comment annotation, and will also try to annotate the video (UA-cam annotation tools are unfortunately limited). Thank you
FYI that earlier in the videio Dr. Seheult did mention that Uracil (U) was in the RNA and not Thymine. Thus I recognized it was a verbal (at least in my case). Thanks to Dr. Seheult for the great learning videos.

Very good explained . Thanks!!!!
Thanks for such a beautiful explanation
Thank you, very informative. One question: what is 5' and 3' ? Could you explain it?
You are soooo awesome!! Thank you for this video
Wow this one was a mouthful even after watching the video you recommended. But I can’t wait to hear how this all plays out in COVID-19.
Corona virus is a planned event.
Excellent video!!!! THANK YOU!!!
What note-taking/presenting program and software are you using to explain this ?
Great primer. Added to our home-school curriculum list.
Just make sure you replace the T's he talked about in his mRNA and tRNA (between 7:05 and 7:10) with U. That was a little error he made here.
Oh goodness! Thank you! I could hug you for sharing this! Viruses are bold f******! I truly appreciate this lesson. It may be basic...it’s a real opener for me & I appreciate this!
Thanks for the mini-review!
That's very informative and easy to understand on the surface although it is very complex.
Thank you! I was very curious and wanted the true facts, which I know you give.
I love science! It's so interesting how it all works together
Looks like I will have to see that video several times to then understand it full.
I would have become a doctor if someone taught these concepts like this
future is online study
I'm a mere layman. This is such a precious lesson. Thank you, Doc.
Such an important video!! thank you for this, I watched it months ago and have not forgot this stuff. I don’t even study medicine (but I can understand all of this, have taken biology 🧬)
Apparently I’m third. I’ve said it before but I’ll say it again: thank you for these videos!
Understanding this process will be a slap in the face for those saying 'muh nCoV is bioengineered because muh HIV genome', forgetting that both Corona and HIV are RNA virus and can be mixed up during viral replication.
Love every one of your videos. Thank you.
Appreciate ur ability to share ur knowledge.....
Always love your videos doc. 😉👍
So good!! thanks so much for this!!
Thanks for the valuable short session
You’re welcome
I wonder if it's possible to request and get such a detailed video explaining prions 😮
This is golden. Thank you. Always wondered where nucular gets around the nuclear so when you set a match to it, it goes boom. Of course the primer cord needs to be a single string ribosome, otherwise it'll just fizzle rather than fissure. Is there going to be a test on this?
Honestly the way you present this, makes me want to delve into this much further. Thank you Doc!
Got it quickly. Tnx great explation
Biology was one of my favorite subject. I love to study it.
My sister took her son to the Los Angeles Childrens and there are lots of cases with people quarantined at that hospital, 2/26/20 12:00pm. Why are these cases not being reported on the news
Ugh. Brought back some “dental school” nightmares. Didn’t like it then, still not too crazy about it. Thanks doc. (I think). Golgi bodies, rough and smooth endoplasmic reticulum, nucleus, glycolysis, mitochondria, translate, never thought I’d use those terms again as a dentist.
Very informative, thankyou.
This is the best. Thanks!
Wist dit 55 jaar geleden al.Kostte heel wat meer tijd om dit op een rijtje te krijgen.🇳🇱
Wow, I am looking forward to other up coming videos from you that relate to this topic! I really want to know why cells allow viruses to use all its facilities to replicate.
Which is the follow up video to this ???
Thank you.This was cery informative.
Regarding translation, in the video you said RNA is AUGC. but when you talked about translation you said tRNA will match up with the ribosomes and you ATA with TAT did you mean AUA and UAU? These videos are awesome. Thank you!
Very helpful!
Thankyou for explaining
Thanks for the refresher course on molecular biology. Many years ago I found it amazing and representative of the power of the universe and how it works on an almost invisible level. Now. with Covid-19 we see the deadly efficiency of how a misdirected biological system can impact not only a cell, an individual but all life.
Your a great at teaching , you should do more biology playlists, help me pass my undergraduate courses haha.
Dear Dr Seheult, I have heard about Redox Signalling Molecules that I’m “told” are involved in cellular communication [and these molecules kill bacteria AND viruses]. Is the communication process you describe in this video what Redox Signalling Molecules do?
Thank you
If nothing else, you are the fastest writer on the planet!
