During which phase of the cell cycle does mitosis occur? O A. Interphase
B. M phase
C. Prophase
D. R phase

M Phase

Explanation:

During the first phase (G1), the cell grows and prepares for DNA replication, which occurs in the subsequent S phase. Further growth takes place in the G2 phase, and finally mitosis occurs in the M phase. G1, S, and G2 are collectively called interphase.
