Put the following stages of the cell cycle in order:G2, S, G1, M.
A
G1, S, G2, M
B
S, G1, G2, M
C
G1, M, G2, S
D
M, G1, S, G2
Explanation: 

Detailed explanation-1: -The cell cycle contains 4 stages; Gap 1 (G1) phase, synthesis (S) phase, gap 2 (G2) phase and mitosis (M) phase.

Detailed explanation-2: -These phases are prophase, prometaphase, metaphase, anaphase, and telophase.

Detailed explanation-3: -G1 phase (Gap 1)-Cellular contents excluding the chromosomes, are duplicated. II. S phase (DNA Synthesis)-Each of the 46 chromosomes are duplicated by the cell. III. G2 phase (Gap 2)-The Cell “double checks” the duplicated chromosomes for error, making any needed repair.
