[@zacktanner5395]

For those curious, it is now understood how the kinetochore microtubules "pull" the sister chromatids: the kinetochores depolymerize the microtubules, which results in the breakdown of the microtubule into tubulin subunits. This effectively shrinks the microtubule, resulting in the chromatids moving towards the centrosome.

[@Phatnaru0002]

Incredible! This should be pinned. It's amazing how almost everything at that level operates by this sort of electromagnetic gravity from the molecular bonds. It blows my mind how many complex processes such a simple force can perform.

[@altrimmamuti9317]

Cool, Thank you

[@whathey3113]

Great, Im also curious about how does the kinetochore attach to a specific centromere

[@adventureawaits3860]

@@whathey3113 kinetochores are disk like structures along the sides of the centromeres

[@Aleksi535]

An easy why to remember the name of the stages is the acronym IPMAT, which stands for, "I Pull Me A Twin." And it actually makes sense... to a certain extent (Interphase, Prophase, Metaphase, Anaphase and finally Telophase). Hopes this helps! Aleksi.

[@ehsome]

hey thanks for this

[@saikumar802]

long live khan academy.................

[@healthfreak18]

I'm a Bio Major and these videos are very helpful to me when I need to review some basic concepts. Thanks.

[@ishanwijesingha4058]

your name shall be echoed through the aeons as a father of biology tutoring

[@triplemgaming5103]

These videos were made when I was just 4 years old. Who knew they would help me so much🙏🏼

[@mariarios5157]

This is amazing! You make more sense than my bio professor, you are very helpful!

[@youseftarek3674]

and ur beutiful ahaha

[@runningwithlola]

These are the best biology videos I can find on KZbin. I don't even look for videos by anyone else because yours are so clear and organized. I have a test on this today and I feel great about it thanks to these videos. I was very confused about the usage of "chromosome" at different phases (referring to single or double strands) and now I get it. I can't thank you enough.

[@victoriaband3968]

This guy is such a blessing and has a gift! I'm studying for my ATI nursing exam and I know of several nurses and read a lot of reviews from other nurses and nursing students to watch his videos. I don't know why my brain doesn't want to retain this stuff when I read it, but the way he explains everything and draws it out, my brain understands and retains the information. Thank you so much sir for making these amazing videos, I could just hug you.

[@DeformedSkier]

We need teachers like this guy in schools, not just people who stand still and lecture the entire period. A good combination of visuals and verbal explanations!

[@imasikujrn-mick6194]

Today I'm having a test including other at mulungushi university Zambia thanks for your work

[@BlandiBoney]

Being a mix between an auditory and kinaesthetic learner this is so unbelievably helpful

[@MrPaddlefeet]

So good. Taught me in 20 mins what my teacher and I couldn't teach me in several months.

[@mizzstargurl71]

Ahhh it works!! Thank goodness!!! I might actually do well on my test on Monday thanks to you!!

[@XHUMBITO1]

Im a Medicine student, and I think that you explain things way better then my proffesor. You give the students a intuition about what is happening, and whats going to happen, and thats the art of teaching. Thank you Sal.

Haha, Neurology resident, soon going to germany.

@@XHUMBITO1 WOW, that's amazing! How is your residency? btw, did you finished your med school in US?

[@JoannaJensko]

Thanks for the help :) you go into more detail than my teachers at college and I prefer it because it makes me understand it more! So thank you!!

[@MelisJoy]

THANK YOU SO MUCH FOR THESE!! YOU ARE A LIFESAVER! I took my last exam, and for the first time I wasn't paranoid the whole time & knew the material! I've noticed in biology, you can memorize the terms, but if you just use flash cards, etc it's not the same as actually UNDERSTANDING the material and how everything works together. If you don't, tests will always get you with a technicality. Example: Centromere, centriole, centrosome. I learned all this material in 20 minutes! Thank you so much!!

[@sierrastorm3242]

I wish my teacher explained things as clearly and as well as you do. Your vast knowledge is inspiring. Thanks for all the help and clarification on any subject I seem to encounter!

[@bear532]

Thank you so much for not just this video but all of them. You are making studying for the MCAT so much easier.

[@LGNpictures]

these videos are magic! i swear i didnt understand a single sentence in my textbook but now after hearing you explain it my textbook suddenly makes sense. THANK YOU!

[@Axle8558]

Amazing, what I couldn't understand in four-weeks of homework, lectures, worksheets, and packets I was able to understand in twenty minutes. Freaking spectacular! Kudos for being able to simplify and teach me what my teacher wasn't able to! Good Job!

[@chanelchain]

Amazing. I'm finishing up my last couple of weeks of Bio then I can move onto my upper div. classes. So no more science for me hopefully for the rest of my life. Thanks for making it happen! You're genius.

[@waduwanfromme]
