In this lesson, mitosis and meiosis are compared in terms of DNA replication, the number of divisions, the presence of synapsis, the number of daughter cells, and the numbers of chromosomes in the products and function.
From a similarity standpoint (between meiosis and mitosis), in both: DNA is replicated and the process consists of phases (prophase, metaphase, anaphase, telophase). On the flip side, Meiosis and Mitosis differ along the following dimensions: number of divisions (1 for mitosis and 2 for meiosis), synapsis is only a characteristic of meiosis (in prophase I), the number of daughter cells produced varies (4 non-identical haploid cells in meiosis and 2 identical cells in mitosis), the number of chromosomes in resulting cells varies (2N in mitosis to match the original parent cell and only N in meiosis as the resulting cells are haploid), and the function/objective of the processes vary (somatic cells are produced via mitosis and gametes are produced by meiosis).

Taught by Professor George Wolfe, this lesson was selected from a broader, comprehensive course, Biology.

what's the difference between thinkwell and mindbites?

[Mindbitesdotcom]

@ctkt21 Thinkwell is the company that puts together these videos, and mindbites is the website where you can access them. Check us out, you'll learn so much!

[huanmieche]

i'm sorry, but can you tell me how much it will be right now to buy the whole BIOLOGY videos package? i wanna have it for christmas ...

[Mindbitesdotcom]

@huanmieche The series that has has all 379 videos in it sells for $198. This is an entire catalog of lessons from basic to upper level theory.

There are also many many other series built from the whole collection that cover more specific topics!

Check it all out by following the link in the description and send us a message if you have any questions!

wow i wish this guy was my teacher then maby i would not be so bord in bio class

[Mindbitesdotcom]

Go to class for attendance then watch our videos to actually learn the stuff! We have awesome lessons on Chemistry, Math, and tons of other stuff too if you have anything else that seems to be eluding your understanding.

Mitosis happens in my TOES.

Meiosis happens in my OVARIES. :P

[jbluntjblunt]

we need more teacher like him in alief

[AirSofter241]

lol i have to watch this guy in school.

[turnitblue2cam]

this video suckkkkkkkkkkkkkkkks

[Manjerh]

i will actually do well on my bio test

[Manjerh]

yay



[ryttut]

@anthonyshock Actually, it has happened before but will not happen again. Never, ever, ever again. :D

[jennxl33]

lol is it true smart people have bad handwriting?

[Nephew8]

thanks for giving a preview of this, no thanks for the payment.

[megangrace33]

THANKS SO MUCH YOU HELPED FOR MY BIO TEST

I'm 13, my sister is 22...we're doing the same thing in science...Its scary.
