It's quite evident that Prof. Wieschaus has a quiet & shy personality; usually that is an issue because lecturers like that are not able to draw the full attention of students but in his case, it's his enthusiasm & passion for the subject that keeps us drawn towards his lecture making it a pretty good learning experience!
Such an informative lecture, you made me really excited about starting my master's degree with a lot of interesting questions about gene expression and how it affects the morphological development of drosophila in an embryo stages. Thanks again Dr. Eric.
I appreciate this. Thanks you tube and The Professor. He soo smooth with his lectures. with this technology we don't even need to pay to go to school. we can just learn at home. =D
@Dalai Llama the reason your hair turns grey is often due to the hydrogen peroxide radicals (toxic wastes) produced in your cells building up in melanocytes and killing them. melanocytes are colour producing cells, they make melanin which is responsible for skin tone, freckles and hair colour. when these cells surrounding the hairs die, they no longer produce colour in newly growing hair strands. so you notice that there is often patchiness in colour and grey etc. because they die in different places. i would say the hair turnover has to do with this phenomenon in that some places retain colour and live melanocytes more than others.
wait why would a concentration gradient of a transcription factor allow activation of other genes ? changing the concentration may change the kinetics but it doesn't change the reaction ? Maybe hunchback promoter has a lower affinity than kruppel promoter ? so weird
so softspoken and interesting...very nice to watch. i am thinking how software can generate structures using morphogenesis, instead of ordinary genetic algorithms.
Sir. thanks for the great information, which is very relevant and important topic,.Could you please explain about the anterior posterior patterning in drosophila and different types of gene expression.
Love the passion put in your lectures. Wish to contact you to ask for help with some online lectures on development. Meanwhile, I can enrich with your iBioseminars. Thanks
Bicoid RNA is all translated within 2hours after behind unanchored? or the protein spread takes 2h? How can the RNA be all transcribed in 1 region, if it is not unchored anymore? in 2 hours, the unachored Bicoid RNA does not spread around the remaining cytoplasm, becoming translated there? Cytoplasm must be like agarose lol
hard to believe that within 2 hours all unachored Bicoid RNA does not spread around the remaining cytoplasm, becoming translated there. Cytoplasm must be like agarose lol
Okay probably not an appropriate comment but I can't stop thinking that Lorl Morella from Orange Is The New Black HAS to be his long lost daughter. Just the way he speaks ;)
He is so nice and so enthusiastic about his topic that it is an absolute pleasure to learn what he explains.
Super helpful! Thank you so much!
I love the fact that despite being a Nobel Prize winner, Dr. Wieschaus' is so humble
I can't emphasize how helpful this channel to me throughout my first year of PhD. Thank you so much!

All must pay attention when he tell us that in 2.5hrs the single cell increases to 6k cells,,,
Prof. Wieschaus is so passionate, feeling grateful that this exists.
Oddly poetic and simply beautiful.

Hey this is the dude my textbook credited for everything...
The video shown in Prof. Wieschaus' lecture is AMAZING
Thanks for the lesson, Professor. Amazing topic, the trapped maternal RNA and the bicoid protein gradient story blew my mind...
I appreciate this. Thanks you tube and The Professor. He soo smooth with his lectures. with this technology we don't even need to pay to go to school. we can just learn at home. =D
This lovely old man present fabulous biology in a romantic way! A lot's of Thanks for preparing this video!

reference?
so so simple and helpful , maybe after 10 years people will never go to university , they will just watch IBIOLOGY
+Nour eddine you mean TH-cam.
Thanks a lot. You have made it so simple and clear. I can meet my class with confidence and clarity.

This man needs to be protected at all costs!!
"it doesn't look very interesting. The amazing thing though is..."
so softspoken and interesting...very nice to watch. i am thinking how software can generate structures using morphogenesis, instead of ordinary genetic algorithms.
I was taught that the hunchback protein was a result of maternal effect gene. Is that correct?
Why is it 6000 nuclei? Would it not be 2^12 = 4096 or 2^13 = 8192?
Perhaps not all nuclei replicate the same number of times
Sir. thanks for the great information, which is very relevant and important topic,.Could you please explain about the anterior posterior patterning in drosophila and different types of gene expression.
Thank you so much! This really helped!
if an iPSC can originate an entire organism, how come mother RNAs/proteins existent in egg's cytoplasm are important for cellularization process?
I have a final tomorrow. Hope to God this vid will teach what i need to know.
what are some potential challenges in terms of technique, performing this kind of experiments. Thanks
This is very helpful. You're a life saver sir!

I like to pretend that the picture of the drosophila egg is life size and that the professor is actually really really small
Where are parts 2 and 3?

Best explanation !!!!!!!!!!!!!!!!!!
Nicely done. Thanks !

My boss was his student ^^
Thanks
Why are only his eyebrows black and his facial hair/ hair on top of head is grey??
Answer that for a scientific question..
Okay probably not an appropriate comment but I can't stop thinking that Lorl Morella from Orange Is The New Black HAS to be his long lost daughter. Just the way he speaks ;)
You are spot on! But I like his wife better (Trudi Schupbach).
He sounds like MIchael Jackson
keep it up
I bet this man knows how to lay the pipe
obvigay
Very boring he turns something that seems interesting into a total snooze fest
