Cell Cycle, Mitosis, and Meiosis… and Giant Chocolate Cake.

Cell Cycle, Mitosis, and Meiosis… and Giant Chocolate Cake.

Hello, and welcome to the Cell-fie Life. Thank you so much for listening! My name is Nikaela and today we are going to be reviewing the cell cycle, meiosis, and mitosis.

If you have questions or comments or corrections, please let me know—the best way to reach me is on Instagram with the handle “thiscellfielife”. That’s this C-E-L-L-fie Life.

Also, if you follow me

on Instagram, I post MCAT prep questions on my story every morning, I hold

giveaways, and I will let you know when new episodes drop.

Please rate, review, and

subscribe. And tell your friends about this podcast. The entire reason I

decided to do it is because I wanted to be able to listen and study while

working, driving, and doing house chores. I didn’t find a podcast that was

providing what I wanted, so I decided to create one. Share with your study


Okay, let’s do

this—mitosis and meiosis.

There are two main types

of cell division that we humans take part in: mitosis and meiosis.

Mitosis is the process

of making new body cells, so it is how two identical daughter cells are created

from a single cell.

Meiosis is the type of

cell division that creates gametes, eggs, and sperm. Meiosis results in up to

four non-identical daughter cells.

When I first learned about mitosis and meiosis, I could not keep their names straight. Which one happens in somatic cells and which one creates germ cells? And, because in science we like to name things very similar to one another to make things extra fun—just wait till we get to centromeres, centrosomes, centrioles, and kinetochores, and we will get to those—I had to think of a clever (or dumb) way to remember which one was mitosis and which one was meiosis.

And, let’s be honest, I

went with the dumbest and most ridiculous way to remember: Have you guys ever

seen the movie Singing in the Rain? There is a song that has the line,

“Moses supposes his toeses are roses, but Moses supposes erroneously...”

And for some reason, I combined “Moses” and “toeses” when I was singing, and it came out “Mos-toesis, and from there it is a really was a short leap to: “Mitosis happens in the toeses”.

If mitosis is happening

in your “toeses”, well, your toes do not need to create sex cells—your toes are

somatic cells. In somatic cells, mitosis is what occurs to create genetically

identical diploid daughter cells.

So if mitosis is

creating somatic cells, then meiosis is happening in germ cells . If my

“Singing in the Rain” song wasn't enough to help you keep mitosis and meiosis

straight meiOOOsis happens in your ovaries—or, you know, testes, if you

are male.

If you guys want to check out the song I’m talking about, “Singing in the Rain”, I’ll post the YouTube clip on the website cellfielife.com. There is also some excellent tap dancing, you know if that’s your thing. To see the whole thing, here’s the YouTube link:


So now that you will

never switch up the location of mitosis and meiosis, let's get into the


A lot of people approach the cell cycle with a pie chart, which is great—I love pie. And I'm willing to bet that a lot of you have seen this breakdown. I’ll post it on my Insta and on the website, but I'm going to approach the cell cycle,
