Interphase | Cells | MCAT | Khan Academy 

Exam tomorrow. Just started studying. Got 5 hours left. Wish me luck lol.

perfectly explained thanks!

test tomorrow. thank you.

Seeing this in online classes ? COVID 19!!

his writing with the mouse is better than my hand writing

I think there should be another name for a "chromosome" when it is replicated into two sister chromatids (duosome?). This new entity is essentially two chromosomes lassoed together and yet we still refer to it as "a chromosome", which can be confusing for students when describing mitosis/meiosis.

Mid-terms anyone?

1:10 "Lets DRAW ourselves a cell" Copy and Paste Lol

I was so confused as to exactly how one nucleus can divide into two because textbooks are so vague. Thank you

Thank you This was clear , very helpful ! And I understood everything even tho english is mi second language so it's double work done

Bio test tomorrow and I only have 2 1/2 hours left to study and i just started oof

I’m in 8th grade taking a living environment course. You’ve helped me significantly in understanding much of what I’ve covered!

didn't know dj vlad taught biology

2:42 "my toe sis"

i laughed so hard on the microphone... guess it'll be really hard to see through that....

2 hours left and i still have a long way to go!

AP Bio 2019?

I really wish I could work for Khan Academy. I have worked in Biology/Husbandry fields and would relish the opportunity to teach. Thank you so very much for all you have given back to the world. Cheers.

I can’t thank you enough for explaining that when the chromosome makes a copy of itself, it’s still one chromosome. I was confused for so long….

i am learning this in 9th standard .......... too rough syllabus for us . ICSE Well thx for making such a nice video.....

I think in Biology interphase should be taught before delving into mitosis and meiosis … bc it gives a better understanding . I took biology and it wasn’t factored in which is why I came to khan bc I am a different learner . If I don’t understand “the how “ I can’t learn the material … so once again thank you Khan/ presenter

exam tomorrow.i just started studying.only 12 hours left.wish me luck

Just finished my GCSEs and NOW I’m getting interested in this stuff

As biology here!?

Finals are monday, wish me luck

I don't know how and why you teach everything better than my college profs

Soo.. exactly when does chromatin form into chromosomes?

my teacher only have us a few worksheets and expected us to learn it ourselves without any material. we are a pre ap class NOT a dual credit class which basically you teach most of it to yourself. this is the most help I've been able to find with accurate information. thank you so much.

didn't you mention about check points

Y'all are here because you're cramming before an exam. I am here because I'm giving a lecture tomorrow and need refreshers.

Thank you so much! Learned a TON

thank you so much got a big test tomorrow

what happens to the mitochondria during interphase? please reply asap

What about the G0 stage of interphase?

Perfect timing :) have a final on this (and mitosis and other stuff) tomorrow

As always, very helpful! The khan Academy videos address the points of confusion in a convenient way. here for example, the confusion about number of chromosomes was resolved for me. Can you also list n and c values? ( n being the number of chr sets and c being the copy number, I think)

Any other college students that didn’t retain any of this information from high school?

Studying, 1 hour before test wish me luck

Thank youuùu exam next week this is going to help me so much

I’m sorry, but the way replication is explained is super shoddy, it could easily confuse someone who had just started delving into the subject into thinking there’s more chromosomes/chromatids than what’s actually the case. In a nutshell, the DNA replicates and what was once a single chromosome now becomes two identical copies which are called the chromatids. However, these two chromatids are not separated yet, but are still attached together at the centromere (a well-known X shape) in a single structure; this structure is still known as a chromosome which is made up of two sister chromatids. They eventually separate in anaphase, which is when they become individual chromosomes.

First

IT WAS VERY HELPFUL

Studying for medicine entrance examination. You saved my studying Khan😅

Very clearly explained! Thank you!

do enjoy his lessons. Don't enjoy using headphones and hearing his swallowing. He is too close to the mic. Thanks for a great explanations though =)

I'm watching this 1 week before my Final Term Exams begin. Wish me luck!

Where is G0 phase sir??????

what about Go interphase?

Im here in 2021 ...... Thanks alot !!!

isn't it the opposite like 1 chromatid and 2 chromatids make 1 chromosome?

Amazing video 👍👍👍

is there a video going in further detail about the protein signals involved in the different stages of interphase? thanks in advance

Wondering why he didn't explain the checkpoints.

Got exam about biology guys wish me luck on the test tomorrow

Thank you man i was so confused how there is the same number of chromosomes.

Isn't g2 when the organelles replicate inside the cell aswell?

If 1 chromosome is copied how it is still 1 chromosome 5:13

Very Helpful

I really want to know what board do u use

You didn't even explain what's goes on in G1, or G2 like why is the cell growing/whats growing. G1- its growing because the cell is making carbs, lipids, and proteins. In G2- the cytoplasm is growing. Or even how the chromatin gets wined up..

in g1 the kromosom is haploid or diploid?

Mid term gang wya

Ooo

These videos are so, so helpful and easy to understand - thank you

Love love love your voice.

Thanks! You helped me for my bio exam tmrw!

neet

awesome vid, thank you:)

a perfect one which i expected . thank u

Hi

Good explanation!👍

Im taking a test rn lmao

So helpful thank you

got resofast tomorrow tnx

Thank you so much ☺️

STEM pa mga Tanga

my.. tosis
