Question

DNA repair enzymes are most likely to be active during which:

G1

G2

Mitosis

Meiosis

Cytokinesis

Answer 1

DNA repair enzymes will be most active during the G1 phase.

explanation- The G1 phase is the first phase of interphase of cell cycle . Interphase is the stage in which the cell prepares itself for the division. After interphase, mitosis or meiosis occur. After this, finally cytokinesis occurs and new cells are produced.

In G1 phase, the cell grows and duplicates it's cellular components. The actual DNA synthesis and repair occur in S phase of interphase. But some also occur in G1 phase also.
