Mitosis

[@soccerfoolman]

You taught me something in 13 minutes that my college professor spent 2 classes going over. Best part is, I understood what you were actually saying.

[@tracyteaches]

This is because as humans we learn better one on one. This is why homeschooled students typically score better on tests and absorb material faster because they have all of their teacher's attention. Studies show the larger the classroom the longer it takes to teach a concept to all the students in a class.

[@ilikerobots332]

yes you are so right about that simple explanation and basic teaching.What took my class teacher over 3hrs to teach all together and i didn't still understand

[@usidbader4556]

hes so slay

[@sorcus2144]

Paul Anderson has actually been to the White House and Space Camp because he won the award of "Best teacher in Montana". Congratulations and thanks for the videos, I live in East London and these videos are still relevant to me :D

[@LoxoVe]

when our teacher doesn't even teach and just tells us to watch these videos

[@kelseystuart648]

+LoxoVe my teacher does the same, she has us take notes on these video's to get our grade

[@jacobjacob5506]

+LoxoVe so tru

[@Angelicmey]

+LoxoVe what!! r u for real?!

[@kelseystuart648]

Yeah, I had to transfer out because my grade was so low.

[@Angelicmey]

That sucks:( I hope you are doing better now.

[@MsOrchidlover]

You are the best professor. You talk very clear, and you explain very well. You never wasted the time of the students. May god bless you.

[@Weisenberg952]

Love how we all came here cuz of our bio teachers assigning this for homework.

[@Little19Kid]

[@ImBiebersBarbie]

you have saved me in so many science courses i can never thank you enough! i wish my professors were half as good as you, thank you so much!

[@elitetech7728]

ImBiebersBarbie Indeed. Mr. Andersen is a phenomenal instructor.

[@stevenshore2244]

U SIR ARE A GENIUS AT TEACHING!

[@gretchenivy25]

seriously. seriously. words cannot even describe how helpful this video was. THANK.YOU.

I was looking for this comment

[@cosmetejeda6001]

Brain and muscle cells only go through mitosis once as we are developing as embryos, afterwards they stay in a perpetual G0 state, meaning that we usually stay with the same number of brain cells for the rest of our life. The reason why neurons and other cells such as these ones don't divide is because a cell has to stop performing its function as it undergoes mitosis, which is bad if the cell dividing is a neuron. Imagine if the neurons in your body begin to divide and stop performing their functions, you won't be able to send an electrical stimuli from your brain to major organs and your heart will stop beating, you're lungs will stop breathing, your brain itself will stop working and so on. That's why we have a limited number of these cells and they can't perpetually divide like the rest.

[@clarasanders1943]

Cosme Tejeda that’s deep

[@HA-wz3ep]

Thanks

[@aif4046]

There is new research that states new neurons are formed when you properly exercise and learn. What's your thoughts here ??

[@MrRapfanatik]

How to learn 40 pages in a 13:35 minutes pre-exam? Just like THIS! Thank you, I owe you one beer!

Thank God for this guy and Mr. Khan, because I would be lost without them. No teacher is better than these guys!

[@mccarthyjacqualine]

Incredible description. All of these videos are easy to understand thanks to the logical metaphors that AREN'T "babied down". Excellent!

[@rayruiz6702]

Your videos are the only ones I can watch when I need to learn something for class and be entertained at the same time.

[@foxyK514]

Thanks for helping me pass my biology tests so far!! Your videos put great visuals in my head and help me understand better!

[@luvdogz123]

My AP bio teacher doesn't even lecture anymore- he just assigns YOUR videos! :) Thanks Mr. Anderson!!!! Biology now makes sense.

[@mikaela10279]

7 people didn't see this until after their exam and failed...that's a bummer. Great videos! real life saver!! :)

[@lehambekele5729]

its become my tradition to watch mr.anderson before a bio test. thx.

[@SnazzyOne25]

This lecture helped me pass my first A&P exam yesterday. THANK YOU SO MUCH for these. I'll definitely be back as I progress through my class, since my teacher isn't the best at lecturing...

[@sstteephanie]

Our professor referred us to use you as extra help - and he was right. You are amazing

[@asadwaseer]

Thanks Mr Anderson. I relied heavily on your videos. They are great, brief, informative and with great delivery.

I don't know what I'd do without your wonderful videos! Probably not get those A's I've been getting in all my classes! Thank you!!!

[@VanillaBalm2116]

Wow, it's been 10 years since you have written this comment... How are you?? Just asking because you know... 10 years 🙂

[@mec-he9en]

My teacher isn't that great for Anatomy and physiology. I watched the mitosis video for the first time and I think your videos are really going to help me! You're a great teacher!!

[@MateiIT]

I have a test tomorrow too,I understood more from your 13 minutes video than i did from all my class of genetics this year :)

[@LolWutShouldIUse]

Thank you for all the explanations Mr. Anderson. My Bio teacher in college doesn't even explain anything to us. He is making us teach the class.

[@MrrRoccckk]

I would fail AP Bio without you. The difference between teachers and well paid textbook audio is astoundingly apparent.

[@inordirectional]

I imagine that it would be amazing to have you as a teacher for a full hour each day the entire school year. These videos do very nicely, though. Thanks for taking the time to make and upload them; they are very helpful.

[@rachelwelch1111]

Your videos are so helpful, please don't stop making them! The diagrams are so easy to understand!! Thank you!

[@Make_smile101]

Your the best . If it wasn't for you Mr Anderson, i would never understand biology! You make Biology so great.

[@corilariz1888]

I love this guy! He helps so much with HW. I like the part at 10:42, something happened in the background and it threw him off for a second.

[@ediwho_]

this is just too good. never stop making them please.

a legend

[@deyanirasuarez6718]

Hi, I am Spanish speaker and I am taking soon my GED test. I love the way you explain it. thank you, it helps me a lot. I love you handsome .

[@mackenzie8165]

"I hope this helped" my guy, you're getting me through college bio because my professor doesn't know how to explain things.

[@tatu5tatu]

Thanks for posting such wonderful explanations!!! You save my life, I was lost with my teacher's lecture, but you clearly gave me a right, clear, and super explanation!! Thanks again :)

[@mars0volta]

And thanks for making these videos! You're doing world education a huge service.

[@laurenvanwinkle4699]

I watched this in addition to the "Phases of a Mitosis" video and it helped a lot! Thanks!

[@tumbaakunosh]

Thanks heaps! cannot imagine how i'd make it through high school without vids like these! i swear, you are amazing!!

[@Joanejw0705]

Thank u so much for this video! It's really helpful:) Juz a reminder, the cytoplasmic division in animal cells occur by inward constriction of cell membrane while that in plant cells occur by outward expansion of cell plate from the middle

[@MC-tp2sl]

your lessons are so helpful for my biology class. You make everything clear and easy to understand. Thank you for taking the time to make this videos. Please never stop makin them. Blessing ur way.

[@jjangs1]

Thank you soo much for posting these videos. I made a playlist of the topics covered in each unit and got an A on my final exam :) .

[@michyaoslikelle]

You are so helpful! I never liked trying to understand biology but watching your videos fully changed that!

[@juliab5413]

I have a biology test tomorrow and this video helped me a lot, thank you! :)

[@giannadoherty2835]

Istg this man is my entire biology schooling. Thanks man.

[@iamjacksrage00]

I love your videos and have been watching for over a year. Thank you for jogging my memory with each new video. I appreciate what you do, thank you bozemanbiology.

[@bearclan9429]

You have the gift to make others understand and appreciate Science. Thanks for making these videos!

[@elitetech7728]

I have a question that any of you may solve. Mr. Andersen mentions that brain and muscles do not undergo mitosis, but how do we get these cells originally? Seeing how mitosis changed us from a single-celled organism to a multi-cellular, chemical powerhouse, how did the "special" cells increase in quantity"?

[@DeezNuts-jh1hh]

they're specialised cells so in g1 they leave for g0 where cells become specialised

[@Maestro455]

+EliteTech When ur young u have a punch of cells called stem cells which are the main source of any cell in ur body and they are cable of forming any cell in ur body so they first copy themselves and then specialise to form these muscle or nerve cells and these stem cells decrease in number the older you get.

[@flowerchild1012]

+EliteTech God did that

[@bronwyngreen119]

EliteTech I think they grow and split first, then specialise. He has a video called "cellular specialization", too FYI

[@ellepicante]

the cells undergo mitosis in the womb and through childhood. then it stops growing for good

[@nataliejohnson1467]

You have the clearest and most concise videos. Thanks!

[@B3bita1215]

Dear Mr. Andersen, thanks for making biology sososoo easy. Sincerely, Your loyal youtube student :)

[@nuttal5265]

I love how you explained!! It so easy to understand !! Thank you :)

[@timmypalmer6727]

Your videos are FANTASTIC!!!! They will be the difference between a C- and an A+. Thanks a ton.

[@barbiedollmichelle]

WOW....you are awesome! The way you are teaching this is just perfect, your videos, the graphics, your drawings...just perfect! I applaud and thank you!

[@inspiricy]

I am having an exam tomorrow, and after watching your video I have a pretty good understanding about Mitosis. Thank you sooo much!

[@ForwardslashTim]

I owe my A in Bio 103 to this man. He explains everything so well.

[@hamzahfaizullah552]

I owe my C to him cuz I would've had an E without him

[@Goddamnitj]

I needed to refresh my memory and this was perfect. Thanks.

[@kureakuma443]

Thanks so much! This was extremely helpful! Good luck on anyone who has a bio test today/tomorrow

[@RoshiR]

All teachers should learn from you... thankyou so much for your ABSOLUTELY AWESOME videos. i love biology.........

[@TheBigcatdaddy1]

Thank you so much for clarifying this confusing topic.

[@AlexThompson171]

you are AMAZING at explaining things. You just covered the content of my second-year university lecture in a fifth of the time. and much more satisfyingly. IF you ever get bored with teaching biology (which i doubt) you should teach people how to teach!!!

Test on Tuesday in anatomy on this. Hope it goes well. These are helpful. Think you could ever put like practice worksheets or fill in the blank/diagram stuff up, Mr.Anderson?

[@Joe-sr2pm]

hi, Mr. Anderson. may you please make a video about the differences between chromosome, chromatin, and chromatid and in which phase do we find each of these??? thank you in advance.

[@pm8635]

Mr Anderson is a genius, I love your school!

[@andshejustsmiled]

i dont think if its because ive been watching him for like a week straight or what but i think he's kinda cute

[@silasmoya4982]

you are the best teacher at explaining!!!!!

[@justakshay2007]

You didn't mention about the regulatory checkpoints. Thank you for the video.

[@kibskibs498]

This video isn't meant for every detail. Its more of a conceptual video that hits the main point of mitosis. You have to fill in the details yourself. Also unless you are talking advanced college level Biology classes you don't need to know much more then this.

[@UnknownsWorld]

This made my studying a lot easier. Thanks for this video.

[@egg7738]

I love your videos, and the are by far the most helpful science sources I have access to. I would just like to clarify what you say at 6:56 and say that Interphase is a stage of the cell cycle but not a stage of mitosis. I know you don't directly say that it is, but I just want to make sure that everybody knows.

[@jamiet1109]

Thank you so much, you have definately explained it much better than my biology lecturer!!!

[@tilknasty9740]

I love you Mr. Anderson!

[@x0cx102]

At 11:10, Bozeman says "plant cells can't really do that, cause they have a cell MEMBRANE..." I think he meant "cell WALL"? Because animal cells also have a membrane, and the wall is probably what's preventing cytokinesis

[@awakeaurora9689]

Yeah

[@jolijnvandijk4755]

SO HELPFUL! Thank you so much! Easy to follow and very informing. THANKYOU!
