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.
You are the best ,thank you so much for all of your videos ,I am a pharmacy student in university of Manchester and you always help me with your teaching ,thanks a lot.
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.
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
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?
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
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 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 cant believe I watch these videos for fun LOL!!! Seriously great vid.... I was wondering if you could do a podcast on pregnancy?? My wife is pregnant an I would just like to understand it better.
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.
Thank you sooo much. I have watched many of your videos on biology and you have a way of explaining this elusive subject in layman's terms that really makes sense. PS- I am in Billings...hello neighbor.
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 :)
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?
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?
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.
At the end he tried to say "I hope that was helpful" but it got cut off and sounded more like "I hope that was hell"
Lol
2:35 bacteria binary fission
5:20 mitosis
7:35 meiosis
9:34 summary
;)
THUNKU
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"
exactly! xD As if when they were naming it they all took turns sneezing and wrote down things that seemed vaguely word-like
may be named it like 1-2 3-4 but so easy for tests lol how creatives
Mind-blowing how all our cells come from just one.
Thank You!!! My teacher doesn't explain the different concepts very well and your videos really help.

no one loves there professor. Everyone loves paul anderson

this is how I spend my Saturday nights! (;
I’m doing this now 7years later

Thank you so much . This video was so instrumental in making the concept crystal clear!
Had 7 test in biology this year and your videos have helped on all of them thanks.
Wonderful explanation as always - he's one of my favorites!
That's why
Mom face+dad face= my face
Hey Bailey, I watched the video
Cell Division = binary fission for prokaryotes, mitosis and meiosis for eukaryotes. Coolio.
This my friend is why sex is important
i love when u say at the end of all your videos: '' And i hope that was helpful''
Wow great timing I need to write a paper on the hayflick limit
Thanks for the video👍🏼
THANK YOU. Great video
Thanks!!! You don't how much this all info matter me. Thank youuuuuu😘😘☺️
Very Helpful, aced my exam with it
Good timing for my assignment thanks =)
absolutely amazing
Your videos are amazing.
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?
good video thanks heaps for the info
Thank you very much, it has increased my understanding of cell division.
Are proteins and them , from the ocean? As shell life with out shells? I just love them too.
Thank you!
Amazing !
Finger crossed for your fore assignments!
Thank you for supplying such a high quality lucid set of resources for people interested in Science,
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
HELPFUL!
Fascinating.

easy stuff with a good explanation

The video was extremely informative and helpful!
Mitosis: splits into 2 cells
Meoisis: splits into 2 cells, collides, then becomes one cell
I cant believe I watch these videos for fun LOL!!! Seriously great vid.... I was wondering if you could do a podcast on pregnancy?? My wife is pregnant an I would just like to understand it better.
thanks
nice video
I have a question. Can you fuse two of the same cells back into one cell?
Make more video :3
Could you go into more detail about what each phases are called such as anophase, telophase and metaphase etc.. Thanks and as always a good vid.

i like it
Thanks!!! Your awesome =)
Great video I linked it in my anaphase video show notes and gave it a thumbs up.
thank you for your lacture everything in your lacture iam understand vrey quick
Meiosis is when one cell produces four new cells
skip ahead to 7:40 for meiosis.
You just saved my education!

Thank you for making these videos!
What a pity. It`s not the translation of mine. I am really upset.

Are you friends with PatrickJMT?
thanks for this video was so helpfull
സ.
mitosis creates two cells, while meiosis creates four
That was really helpfull

excellent video
it's thanks to you I'm passing bio XD
thank you very much ,It is very good.
Imagine. Living in the future
very helpful thanks
ag bio ppl?
Well done
Is it possible u can do a video on epistasis? Many thanks
I have a question so in meiosis do we always start the 46 ? I get confused when we have questions about the chromosones
yea. meiosis starts w/ 46 but it doubles to 92.
Gr8!!!!! V.helpfulllll!!!!!!!!!
Just Great
Can you do something about micro RNA?
Awesome!
i am Thai student thank ^^
thank you thank youuuuu
im so uncomfortable

Thank for the video. By the way, you look tired,Mr. Sciencetist.
i like itt
me too! :) LOL not the pregnancy part tho
Lollol
And yes I cite your videos lol
btw thnks :')
what the what is that
