During which phase(s) of cell cycle, amount of DNA in a cell remains at 4C level if the initial amount is denoted as 2C?
A
$G_0$ and $G_1$
B
$G_1$ and S
C
Only $G_2$
D
$G_2$ and M
Detailed Solution
DNA replicates in S phase, raising the content from 2C to 4C.
It stays at 4C through $G_2$ and M phase until the chromatids separate and the cell divides.
