Cell Division

Paul Andersen explains how cells duplicate through the process of cell division. Prokaryotic cells (like bacteria) duplicate through a process of binary fission. Eukaryotic cells (like you) duplicate body cells through mitosis and create sex cells through meiosis.

Have a great day my friend! 😆

These names kill me. I feel like when they discovered all this they were like "let's pick names that are in no way related"

[@champo865]

exactly! xD As if when they were naming it they all took turns sneezing and wrote down things that seemed vaguely word-like

[@juliocesarcastillot]

may be named it like 1-2 3-4 but so easy for tests lol how creatives

[@ranchandmustard]

Mind-blowing how all our cells come from just one.

[@MrInvisibo]

Thank You!!! My teacher doesn't explain the different concepts very well and your videos really help.

[@Bernadettefull]

You are so cool and giving such an advantage to your students. I am taking a class with a Harvard PhD, and a Berkeley postdoc.....and he confuses me much more than helps me to understand. He makes me feel so shut down and bummed out! All teachers could take a lesson from you!!! THANK YOU VERY MUCH for your work and dedication!! You are an inspiration to us all!!!! Thank you!!!!! I love my teacher anyways. We are all on our own growth paths.

[@apurvabharadwaj2940]

Thank you so much . This video was so instrumental in making the concept crystal clear!

[@jbarkerhill92]

Thanks for the video. I learned about this stuff back in high school, but didn't think much of it.
But I have a renewed interest in genetics. It's a fascinating field that I think holds many of the secrets of life.
Also, it's mind blowing that all organisms start as a single cell.

[@kaganshepherd1902]

jbarkerhill92 IKR!! I'm just starting to learn this stuff and this vid helped a lot...I just started 7th grade a few weeks ago and this stuff is SO confusing to me...I'll get the hang of it...well, HOPEFULLY

[@henrynguyen3137]

absolutely amazing

THANK YOU. Great video

[@humailali8630]

Thanks!!! You don't how much this all info matter me. Thank youuuuuu😘😘☺️

[@geraldillo]

Great video! thanks for your thorough explanation! I have a question though: is cell division (except for Meiosis) always binary? Wouldn't it be faster if cells would triplicate or even do do higher number of multiplication or is binary multiplication the most efficient way?

[@zoecooper123]

Good timing for my assignment thanks =)

Thank you! That was really helpful! When it comes to stuff like this I'm lost and it just sounds like a foreign language to me! My teacher didn't explain it well to me! And so now I have a better sense of what we're talking about! Thank you lots

[@oliviawhite7581]

Cell Division = binary fission for prokaryotes, mitosis and meiosis for eukaryotes. Coolio.

[@lorcresiakonopasek9793]

[@GANSTA6033]

This my friend is why sex is important

[@alextucker3976]

Very Helpful, aced my exam with it

[@ZimDaMan]

Ok so i understand why in mitosis the somatic cell starts off with 2 chromosomes (since its diploid) then through interphase the chromosomes double and become sister chromatids. But how come with meiosis you start off with 4 chromosomes straight away? Did interphase occur before that and you didnt mention it? and if so why arent they paired together like the sister chromatids in somatic cells? Please explain. Thanks :)

[@nintendude1994]

Wow great timing I need to write a paper on the hayflick limit

[@Patchworkz22]

Thank you for making these videos!

[@jarbincks6715]

Mitosis: splits into 2 cells
Meoisis: splits into 2 cells, collides, then becomes one cell

[@MsAcrowell]

You are a great teacher! I wonder how you have the time to make all these great videos, I aspire to be a great teacher like you. How long have you been teaching? I never have enough time to accomplish my own videos. Thank goodness I can use yours! Thanks again, my students enjoy them.

I have a question. Can you fuse two of the same cells back into one cell?

thank you for your lacture everything in your lacture iam understand vrey quick

[@WorthlessWinner]

I don't see how he could beat the piece NOVA did on it. I'm sure he'll get round to it. Better to do the whole of noncoding RNA at once, since it all seems involved in regulating expression, often using the same proteins. Small, single stranded RNA is used to target Argonute proteins to complimentary sequences; one Argonute protein (RISC) stops translation of mRNA, another (RITS) directs epigenetic silencing of DNA. Lots of ways the small RNA can get there, most feed to the same paths though.

I need help... I graduated H.S. in 1977, (yes, i am old). I am in college, my hopes are to become a nurse. I am failing biology 111. What REALLY hurts, is that I LOVE biology. I found your videos, and it really helped, but I need an A in bio 111. I need help learning how to learn biology.... ! Any video's on that?

[@murd7034]

Hi, I know this is from 9 years ago, but we had to watch this video in our bio class, and I saw your comment. how did it end up going? did u become a nurse?

It's another world beneath our feet. The little people as we say in Ireland. Quite amazing, we're giants standing on the shoulders of cells. Nearly forgot to say thanks for the video.

[@fightingninja15]

it's thanks to you I'm passing bio XD

[@WorthlessWinner]

I hear the "DNA attaches to the cell wall" thing in binary fission has no evidence for it and other mechanisms are preferred now? Apart from that, great video.
I love how complex something as seemingly simple as binary fission is. So many genes are involved to regulate it and remodel the cell wall if it's present, as reproduction is so important.
Many cells still have a simpler 'blebbing' division programme, that gets activated if you remove the cell wall with penicillin selection.

[@amrfarahat4429]

thank you very much ,It is very good.

yea. meiosis starts w/ 46 but it doubles to 92.
