Problem 3: Cell Cycle Sequence










ans:
A. G1 to G2 to S to M to cytokinesis
Incorrect.
The correct sequence has G1 as a preparation for S and G2 as the time between the completion of S and entry into M. Cytokinesis occurs after the other stages to create two daughter cells.

B. G1 to M to G2 to S to cytokinesis
Incorrect.
The correct sequence has G1 as a preparation for S and G2 as the time between the completion of S and entry into M. Cytokinesis occurs after the other stages to create two daughter cells.

C. G1 to S to M to G2 to cytokinesis
Incorrect.
The correct sequence has G1 as a preparation for S and G2 as the time between the completion of S and entry into M. Cytokinesis occurs after the other stages to create two daughter cells.

D. G1 to S to G2 to M to cytokinesis
Correct.
The correct sequence has G1 as a preparation for S and G2 as the time between the completion of S and entry into M. Cytokinesis occurs after the other stages to create two daughter cells.
