Interkinesis differs from interphase in absence of

Options

A. DNA replication
B. Histone protein synthesis
C. Centriole duplication
D. Both (1) & (2)

Answer

To solve the question regarding how interkinesis differs from interphase, we need to understand the definitions and processes that occur during both phases. Here’s a step-by-step breakdown:

### Step 1: Define Interphase
Interphase is the phase of the cell cycle where the cell prepares for division. It is divided into three sub-phases:
- **G1 Phase**: The cell grows and synthesizes proteins necessary for DNA replication.
- **S Phase**: DNA replication occurs, where the cell duplicates its genetic material.
- **G2 Phase**: The cell continues to grow and produces proteins required for cell division.

### Step 2: Define Interkinesis
Interkinesis is a phase that occurs between the two meiotic divisions (meiosis I and meiosis II). It is a short resting phase where the cell does not undergo DNA replication. Interkinesis can also be referred to as interphase II.

### Step 3: Compare Interphase and Interkinesis
The primary difference between interphase and interkinesis lies in the occurrence of DNA replication:
- In **interphase**, particularly during the S phase, DNA replication takes place.
- In **interkinesis**, there is no DNA replication; the cell simply prepares for the second meiotic division.

### Step 4: Identify the Absence in Interkinesis
Given that interkinesis does not involve DNA replication, we can conclude that interkinesis differs from interphase in the absence of DNA replication.

### Conclusion
Thus, the correct answer to the question is that interkinesis differs from interphase in the absence of DNA replication.
