Which of the following phases correspond to the interval between mitosis and initiation of DNA replication

The correct option is D $G_1$-phase

Cell cycle basically consists of two phases-1. Interphase 2. M or Mitotic phase

Interphase is the most active stage of the cell cycle where cell growth and DNA replication occur. It is divided into 3 stages- 1. G1 phase 2. S phase 3. G2 phase.

A. S phase is a phase in which synthesis or replication of DNA takes place.

B. G1 phase is the interval between mitosis and initiation of DNA replication. In this, the cell does not synthesize or replicate DNA but remains metabolically active.

C. G2 phase is the second gap phase present between S and M phase.

D. M or mitotic phase is the phase where actual cell division takes place.

So, the correct option is B.
