a thousand thanks to you for all the work you do. it is really great. clear voice, nice explanation, correct pace and above all videos on most of the important subjects.
This work is inestimable in worth and importance, I only wonder why its not getting more views,likes, shares and subscriptions?

ye, school's not about learning the material. It's about figuring the quickest easiest way to get the highest scores on all subjects and tests to pass. I wish I knew that when I was in school. I always made it much harder on myself than I really had to make it. And my grades were really bad as a result.
Theres certainly a lot to unpack with these critiques on the education system. Some focus on paths to college and minimise the importance and satisfaction that are in trades, while others simply are trying to change the world through students to fit their own narcissim. But many times you find schools being essentially care facilities just trying to get through to the next day.
you are amazing! this helped me so much. i don't know why you don't have more subscribers... i think you are better than any other educational youtuber i've seen!
good question! i think it's an area of active research. but it's certainly due to some kind of conformational changes on the part of some proteins once binding occurs.
Professor I searched on the internet and found this article, 'Myovirus bacteriophages use a hypodermic syringe-like motion to inject their genetic material into the cell. After making contact with the appropriate receptor, the tail fibers flex to bring the base plate closer to the surface of the cell; this is known as reversible binding. Once attached completely, irreversible binding is initiated and the tail contracts, possibly with the help of ATP present in the tail,[4] injecting genetic material through the bacterial membrane. The injection is done through a sort of bending motion in the shaft by going to the side, contracting closer to the cell and pushing back up.' So, they contain ATP from their earlier host.
Thanks for the information I founds this very interesting I am just a retired guy trying to understand a bit more about a virus and thanks to your great video I now do.
This is my theory with respect to viruses. Just as in computer science a computer system and the language it uses is created by an engineer. So they create an Operating system based of complex code and release it to the public to be used for various purposes such as: accounting, data entry, editing programs etc. Then a jealous engineer of the same knowledge level analyses the creators code and decides to engineer another piece of code that will disrupt the functionality of that OS created by the first engineer. This is when a computer becomes infected with a virus and it starts acting crazy. Biological viruses like computer viruses are engineered by someone with the knowledge of DNA coding. This explains how viruses can affect specific parts of a living organism and are designed to disrupt a specific functionality within that organism. This is why you have viruses that attack the liver only (hepatitis), the respiratory system only(influenza and the like), the reproductive system only (gonorrhea) etc. HIV is a master piece of viral engineering affecting a human's Immune system, the system which function is to fight off deseases that infect the human body. This means that from that point forward once infected with HIV the human body will no longer be able to fight deseases on its own and will always need aids from medicines and any deseases threatens the life of the sick person with HIV. Now let's think about who do viruses benefit? I'm a computer engineer but I like Biology.
This man is so brilliant in explaining any topics of physics, chemistry , biology ,maths and so on . I have been inspired a lot by you and i wanna grab knowledge of all phy, chem, bio, maths together .More respect to you!❤️
It looks horrifying, like a microscopic robot that is out to hunt down and kill every living being it encounters. But there are good news. Bacteriophages only attack specific bacterias and not living cells. Bacteriophages do not attack human beings as we are too much of a target for them. In fact, right now scientists are researching ways to use bacteriophages to fight bacterial diseases in the body. They are kind of the good guy in this fight.
Thank you soooo much for creating free content for medical students. Many students like me can not afford even low membership fees of websites that have been designed for medical students and your channel is one of the most precious resources for us♥♥♥🙏
good video, I would add a little data: there are some viruses that can have a symbiosis with the host cell to the point that they can repair it or save it from death
You are amazing sir! thanks I can understand your accent too bro.... "work for all not for the privilege only"!!! .... I wishes if every one do like you because many of the professor they post here, it is hard to listen them and also they talk so fast and it is difficult to understand them.. thanks again...
There is a video made by Veritasium that shows the copying of DNA on the molecular level. It's amazing how something so complex can be done by little machines that have no capacity to think, just react.
@N K Idk what you mean "saddest", and you don't need 70IQ just to remember a piece of information... That's not a sad thing. It's just you won't ever need to know what H1N1 in most jobs, so there's no point of learning it
From a speculative consideration the intonation , pressure , emphasis and accent of his voice is actually not only guiding the viewer or host about the important ideas being presented as he leaves aside other less important but also he seems to even teach how to speak giving to the viewer a particular and colourful profile. Not even to say that in the actual global viral event the Intelligence of viruses also seem at moments to be by the same biological mechanism imprinting changes from the political to the social paradigma.
Thank you so much for your explanation, it is really dynamic and really got me focused. Honestly, I am being "forced" to study biology in english even though it's not my native language bc I can find any good explanations in my language cuz everything they explain is theory, and cells, virus and bacteria aren't things you can learn only reading. Thank you so so much.
It is amazing how something so simple and uncomplicated can a fool a substantially complex system like the human body. Wonder why it evolved like this.
sometimes simplicity is best, the more complicated the system the more holes in its defences, virus are so simple that they have no way to be infected or preyed upon.
Teachers teach the simple lessons of virus along with biology in high schools for teenagers to learn the basics of virology. In colleges, professors teach a varieties of virology than ever before because so much knowledge about viruses and diseases has been updating rapidly. This year 2020, the spreads of corona virus have been escalating serious problems to the world with life, death, fear, confusion, lockdowns, and downward economy since December 2019. UA-cam videos about viruses are helpful for individual who wants to learn more.
I came here because the ongoing Covid-19 got me interested in how viruses work. Very informative. Thanks and stay safe. However, if viruses evolved back when singular cells came about, how come they didn't kill the singular cells back then?
You do an amazing job of teaching and your explaination is....I am just very greatful to have found your youtube. I love learning and can't seem to get enough....I work at a hospital and when I tell the other nurses that a virus is not living, they just all laugh at me, and ask me what school did I graduate from? Keep them coming and thank you.
@@fungames24 A report of 2019-nCov genome sequence report shows 4 HIV-like structures in the S protein segment on the viral membrane. This is the site for binding with the host cell RNA to disguise the virus to cross the host cell membrane through "endocytosis". These HIV-like structures have not been observed in other known coronaviruses but are found in HIV virus. This may happen through random mutation in nature. The propability of this freak mutation with not one but four HIV-like protein structures is extremely low and would take a very very long time unless the HIV-like protein structures were the result of manipulation in a high grade biotech lab for example. Even more intriguing is the claims in the US, Thailand and China that few 20019-nCov infected patients responded very well when anti-HIV drugs (e.g. Interferon) are used in combination with supportive treatments . From this very useful video, we can deduce that blocking the HIV-like protein structures on the Wuhan virus prevents the virus's ability to hijack human cells to replicate itself!!!!!
Molecules react with one another. Is that doing something? Are molecules alive? No, they aren't. And the mechanism of viral injection isn't even a chemical reaction. It's the result of a conformational change in the proteins in the "legs" due to recognition by bacterial receptors. Stop spamming this video with comments pretending that you understand biochemistry.
In the lysogenic cycle, the host cell unwittingly transcribes the prophage's DNA everytime a nuclear proccess occurs, this create something that roughly translates to parasitic symbiosis. The host cell is asymptomatic.
Very nicely done video. the nice graphics and information really clarified a lot of things for me. Did I miss it or did you explain the difference between the RNA/ DNA in the double protein coat capsid in the mitochondria of the cell? There are so many unfamiliar terms, to me, in cellular biology that sometimes I have trouble understanding certain aspects. But thank you, I have learned a great deal from your video! When I said "Did I miss it or did you explain the difference between the RNA/DNA in the double protein coat capsid in the mitochondria of the cell" I meant - Did you explain the difference between viruses and the RNA/DNA in the mitochondria, that have the same structure as viruses have?
Maybe that modified viruses could be used to fight bacterias, using their ability to target specific cells. Maybe that modified retroviruses could be used as well, to repair corrupted cells. DNA-programming should be very usefull in the next future. And DNA-based computers should do it.
I spent 15 years at UNMC as an electron microscopist. Did early research with HIV. Cool to see teaching videos like this.
That's so cool
As someone who has been in the sciences for 45 years I say ‘thank you’ and rate this as ‘excellent’.
Then why so many thumbs down? Its just information.
