Wonderful explanation, thank you!
I can't understand why the size increases after adding H1 from 10 to 30 and why is it even useful ?
really helpful
Thanks You
Professional
Omg! U are a genius. Thank you for making this video!
Glad it was helpful!
In which book , are these lectures ?
wow thank u
Glad it helped.
There is not much talk about the importance of healthy motor molecules to help with Mitosis, Meiosis and Mendel. Like the signal switch to turn on by a motor molecule of Mitosis
Correct. That is an active research topic for the cell biology of mitosis, meiosis, all of the special cases (such as asymmetrical cytokinesis) and all the ways it can go wrong (as in non-disjunction).
@@janineleblanc-straceski3181 i love to talk to you more if possible about such a subject. i have no degree i cant afford college yet. I just a deep passion for helping Cancer patients that dose more good than bad some day. so the health of the motor molecules leans alot on the ATP for them to get around and Cancer has alot of factors one is it is a uncontrolled situation which is connected to the Mitochondria they activate caspase which helps with Apoptosis . so in short test the health of the motor molecules mainly the Kineasen and Dynien can be tested because the motility of the mitochondria is as far as my studies show done only by them. There is more i will see if i can chat with you more first

@@janineleblanc-straceski3181 thanks
Very interesting statement saying Viruses can transfer genetic material from one bacteria to another i usually thought viruses try to take control of there own RNA to spread there genitic material ? Can viruses transfer of Mitochondria DNA one to another ?
The only video that helped. Thanks a lot. :)
I’m glad you found it helpful!
There is an omission around 6:12. In the transition to the next slide I neglected to emphasize that the table contains data from the F2 generation - the offspring of the mating between the heterozygous female fly and the hemizygous male with all three recessive mutant alleles.
I can't thank you enough for these videos!!!!!!!
I very glad they are helpful.
This is quality content!
Thank you so much. I've been thinking of a way to find everything related to this topic in just one video. Thank you.
Thank you so much for this video! It helped me soooo much.
Glad you found it helpful.
Where's your website?
Well explained and nice slides
Can you tell me which books should i use for bacterial genetics
Can you please tell us how all histone intract to each other in octamer and how h1 is bound
I have no words to thanks you You are save my life
i seriously wish you were my professor
Well, I guess I am! Good luck!
Wow all of what i can say all the respect to you you made me understand the topic not memorize it with no understanding and forget it the next day at first i thought it's a pretty hard subject but your simplification of the topic with pictures showing us the bridges between the bacteria and the experiment that was done made me understand what's going on thank you so much please share more videos we need more people like you i'm an auditory person and love learning from watching videos you deserve a big like thx a lot again
Thank you for your kind words. I am happy you found them useful.
Finally all DNA level structures well explained! No others videos like this one.
which book are you using?
Concepts of Genetics by Brooker
Thanks Prof.Straceski !
You are welcome!
Very Good ! Thanks
Glad it helped!
If I have the length of a protein given as the numbers of aminoacids, can I say that the corrisponding mRNA has a minimum length of the number of the aminoacids times 3? Or does the UTRs also have a set minimum length?
UTRs contain at the minimum the Kozak sequence for ribosome binding at the 5' end and the AAUAAA cleavage and polyadenylation site at the 3' end, and then the subsequent poly A tail (usually). I 'm not aware of any measurements of average or minimum length, but I'm sure there are some!
Why doesn't the endonuklease cut just the tRNA out instead of cutting it with that extra bit of intron on it? Why the extra step with the exonuklease?
The “why” question is a tricky one. There is seldom a satisfying answer. The short answer is that there is no good explanation that has been elucidated right now.
@@janineleblanc-straceski3181 Hahaha fair enough! Thank you so much for your amazing lectures and also replying to all questions! I really appreciat it <3
why does the DNA only gets gut between histones? What prevents it from beeting cut at the curled around parts? Also Thank you for these awesome videos!
That is a great question. As DNA is replicated - or transcribed - nucleosomes dissociate from the DNA and reform behind the polymerase. There's a lot going on at the replication fork and the transcription bubble!
U r aweersssome
I’m glad you found these helpful.
Mam u r really aweeeeeeeeesssssoooommmmmeeee
Thanks!
U r really aweeeeeeeeeeessssssssooooooooommmmmmmmeeeeee
I love your course! Thank you for sharing! I just wish the music in the background was absent. This one is quite distracting.
Sorry about that.
I like the explanations
It very good Hello Dr LeBlanc Please 🙏 I need this unit 14B by book or PDF
The text is Concepts of Genetics by Brooker
@@janineleblanc-straceski3181 how to get it?
One of the most useful videos on this topic!
Thank you. I'm glad it helped.
Thank you for the posting these lectures. Have watched each one and found them to be very helpful.
I’m so glad you found them helpful!
very good explanation
Glad it helped!
Thanks for posting these vidoes, doc. Very helpful.
kitsand Thank you!
It means that the length of chromosome will become longer and longer and include much more useless information?
Chromosomes shorten overtime, at the telomeres.
@4:00 very good explanation about where and how to choose position to split the chromosome.
what a beautiful explanation :)
Thanks a lot for this playlist, its quick way to brush up the concepts. Is there any possibility to get these presentation slides from any of your sites? Thanks in advance.
Firstly thankyou mam , in first video lecture u told about ppts so can u provide link for that 😊
Best lecture on transposons on whole youtube
what are the protiens responsible for adding or putting the newly synthesized dna aroung histone is this occur at the same time when the new stard is just synthesized a histone protien in added?
That is a good question! There probably are some chaperone proteins. The newly synthesized DNA is immediately rewound around nucleosomes. Old nucleosomes are stripped off the template, broken down into half-nucleosomes that retain their epigenetic modifications (methylation, acetylation etc.) and mixed with brand new histones. Enzymes recognize the half- modified nucleosomes and duplicate the modifications on the new histones. (Re-call that a nucleosome core is an octamer of 2 each of H2A, H2B, H3 and H4.) That is how epigenetic modifications are passed from mother to daughter cells.
thank you so much. you are a saver
Very glad you found it helpfull.
@@janineleblanc-straceski3181 thank u sooo much
