Problem 1: Cell Cycle Stages









ans:
A. G1

G1 cells are preparing for S

B. S
Incorrect.
S means cells are in the process of replicating DNA.

C. M
Incorrect.
Cells in M are in mitosis, and dividing the chromatids between daughter cells

D. G2
Correct.
Yes, S resulted in the duplication of each chromatid. Since there is only one centromere on the sister chromatids, we still call them one chromosome. When completed, the cells are in G2 and preparing for M.
