A group of students are diagramming the cycle of a cell. What phase would they diagram as actually synthesizing deoxyribonucleic acid (DNA)?
A) S phase
B) G0 phase
C) M phase
D) G2 phase
A
Feedback:
The next phase, called the S phase, involves the actual synthesis of DNA, which is an energy-consuming activity. The cell remains in this phase until the amount of cellular DNA has doubled. The G0 phase is considered the resting phase of the cell cycle. The M phase is when cell replication occurs. The G2 phase is when the cell produces all substances it needs to replicate.
