It is important that the DNA is copied from the cell that is going to divide. This is how you make more cells and you physically grow.
ACCESING DNA...MITOSIS READY
CELL #002
Before you learn the steps of mitosis, you need to know that there is a very important cell structure inside all your cells called a nucleus. The nucleus contains your DNA.
The thing is though, you have a lot of strands of DNA. I mean, DNA is what makes you YOU, right? So there’s going to be a lot of it.
welcome to the nucleus
ANGELA'S NUCLEUS
If you want to bake a cake, you would need to learn it from a cookbook. The cookbook will tell you what to do. DNA is like a cookbook for your body.
CHROMOSOMES! AT YOUR SERVICE
JUST TWO INGREDIANTS!
You want to make sure that you have the same DNA in your new cells as you did in your old cells.
HOW TO MAKE CHROMOSOMES
Your body has a lot of DNA and all of that DNA needs to be copied to do mitosis. So what is going to happen when there is a lot of it?
DNA is organized into small units called chromosomes that have a shape like “X”s.
DNA
A chromosome is made up for DNA and proteins. You can find 46 chromosomes located in most human cell nuclei. Nuclei is the plural form for nucleus. Not “nucleuses”
