The phase corresponding to the interval between mitosis and initiation of DNA replication-

Answer

To answer the question regarding the phase corresponding to the interval between mitosis and the initiation of DNA replication, we can break down the solution into the following steps:

### Step-by-Step Solution:

1. **Identify the Context**: Understand that the question is asking for a specific phase in the cell cycle that occurs after mitosis and before DNA replication begins.

2. **Recall the Cell Cycle Phases**: The cell cycle consists of several phases: G1 (Gap 1), S (Synthesis), G2 (Gap 2), and M (Mitosis). Mitosis is followed by the G1 phase.

3. **Define the G1 Phase**: The G1 phase is also known as the first growth phase. It is the interval where the cell grows and prepares for DNA synthesis.

4. **Describe the Characteristics of G1 Phase**: During the G1 phase, the cell is metabolically active, synthesizing various types of RNA (such as mRNA, tRNA, and rRNA) and proteins. This phase is crucial for cell growth and preparation for the next phase, which is the S phase, where DNA replication occurs.

5. **Conclude the Answer**: Therefore, the phase that corresponds to the interval between mitosis and the initiation of DNA replication is the G1 phase.

### Final Answer:
The phase corresponding to the interval between mitosis and initiation of DNA replication is the **G1 phase**.
