A cell has 12 chromosomes at the end of mitosis. How many chromosomes would it have in the G2 phase of its next cell cycle?
-6
-9
-12
-24
-It depends on whether it is undergoing mitosis or meiosis
I picked 24, because G2 occurs after S, and it would have already doubled its DNA for division..
But the book says its 12
Can someone please shed some light on this?
Is it because each chromosome consists of two sister chromatids? and thus since it has 24 sister chromatids, it still has only 12 chromosomes?
I am usually good at this stuff but now im confused...
