Cell Cycle, Mitosis and Meiosis

We're all a bunch of cells watching a bunch of cells talking about a bunch of cells. Huh.

I know your videos dont replace my book but they sure demonstrate clearer concepts in addition to examples I can relate to. You sure make learning more fun and it doesnt make me want to fall asleep. Keep up the good work on these videos, they sure are a great help. Even for a college student such as myself.

[@conorbitz7620]

No wonder my teacher only rarely shows us one of his videos, cuz Mr. Anderson here is a better teacher...anyway, thank you!

i love his teaching way he makes it very easy and simple and direct too

[@Cocochanew5]

My teacher isn't great and tells us to use the internet to learn the lesson... This is much better than any teaching!

[@Absbs123]

This is one of the best explanation ever made. Thanks Mr. Paul Anderson

Dude, I don't know what I'd do without your videos.... well probably read each chapter several more times. Thank you so much.

You did a great job explaining cyclin! I was really struggling with that

I love your tone of voice, so peaceful and confident! I have learned a lot from you. Without your videos, I would have never passed BIO with an A+!! Thank you Bozeman!

my god dude, you don't know how helpful your video is. i've midterm exams tomorrow on this subject :) THANK YOU SO MUCH. now i'm gonna send this vid to all my friends!!

So this is my main way of studying for my AP Bio test, and my teacher shows your videos every time we move into a new unit. Thanks for making it understandable!!!

I am learning things about Cyclin and what exactly it does that my College 1610 professor and required textbook never explained well or at all... Mr. Anderson, you teach Science better than many of the professors at my university.

YOU ARE AN AWESOME TEACHER!!!!! WITHOUT I WOULD NOT PASS THIS CLASS!!

[@dogzlf]

Great video! BTW at 10:45 you might want to make a video note as to not confuse people. You said mitosis when you meant miosis.

The way you represent teaching the topics.................... is gr8..

[@CareyReeve]

I second this answer. The ploidy level (the number of duplicate chromosomes) doesn't change when the chromosomes replicate. Many organisms (mostly plants) do have many copies of each chromosome, though. Wild strawberries can have 2, 4, 5, 6, 8, or 9 copies depending on the species. Aside from this slip-up, though, this is a great video that really makes the contrast between mitosis and meiosis clear.

[@hannahelarabawy7550]

You succeeded to teach me what I didn't understand after 3 weeks of explanation in 13 minutes. THANK YOU SO MUCH! I am now ready for my final tomorrow :)

Thanks! my teacher is not very good at well, teaching, so this really helped!

[@amberduvall9966]

After Meiosis I the daughter cells are reduced to haploid. While there are still 2 sister chromatids in each cell, they have been separated from their homologous pair and thus reducing the ploidy from diploid to haploid. Thus by your illustration we would start with 2n=4 --> then become 2n=8 when the chromosomes duplicate and then into 2, n=4, cells after Meiosis I which would result in the four haploid cells each n=2 after Meiosis II
