1
Q

A
G1- first checkpoint, cell spends most of its time growing and gaining nutrients.
S- synthesis, this is where DNA begins to copy
G2- prepares to divide
M- mitosis
2
Q
What happens in G1
A
At the end of G1 the cell checks if it has enough nutrients to onto the next stage
If not the cell preforms apoptosis
3
Q
Apoptosisis…
A
Program death, which removes unnecessary cells during development and removes whhealthy of damaged cells
4
Q

A
Cell division that results in daughters cells, each each having the same number and kind of chromosomes as the parent nucleus
5

Prophase
A
First stage of mitosis
- Nucleus disappears
- chromatin condenses into chromosomes
