stages in the cell cycle
Hello.. It appears I'm stuck on another question. I've figured out 3/4 of it, but I can't seem to find ANYWHERE in my textbook, anything about the stages of the cell cycle and cancer. If you can help me, that would be great.
Which stage or stages of the cell cycle do the following statements refer to?
G0 STATE a. Cells usually arrest here when they stop dividing.
G2 b. Chromosomes are visible.
S PHASE c. Chromosomes are doubled for the whole stage.
G1, S, G2 d. The stage(s) included in interphase
_________ e. Cells usually leave this stage(s) when they become cancer cells.
I have no idea?!! Any assistance would be muchly appreciated!
Thanks everyone!

Re: stages in the cell cycle
Hello,
Chromatides are condensed in prophase sub-stage of M (mitosis) phase of cell cycle. Thus, chromosomes are visible in M.
The answer is G0. Because, cancer cells divide like normal cells do. But, they aren't controlled properly so, they accumulate mutations in genome. However, they are more active in terms of dividing and are rarely quiescent and arrested in G0.
