Interphase involves DNA replication whereas interkinesis does not. Ans C is correct.

Introduction:
Interphase 1 and interkinesis are two distinct stages of the cell cycle that occur during meiosis. These stages are important for the division and replication of genetic material. In this response, we will discuss the events that are common between interphase 1 and interkinesis and identify the event that is not common.

Interphase 1:
Interphase 1 is the longest phase of meiosis and consists of three subphases: G1, S, and G2.

1. G1 phase:
During the G1 phase, the cell grows in size and prepares for DNA synthesis. The centrosomes also begin to replicate.

2. S phase:
In the S phase, DNA synthesis occurs, leading to the replication of the genetic material. Each chromosome is duplicated, resulting in the formation of sister chromatids.

3. G2 phase:
During the G2 phase, the cell continues to grow and prepare for cell division. The organelles, such as mitochondria and endoplasmic reticulum, also replicate.

Interkinesis:
Interkinesis is a brief resting phase that occurs between meiosis I and meiosis II. It is similar to interphase, but without DNA replication.

1. Growth in cell:
During interkinesis, the cell continues to grow in size, similar to interphase 1. This growth is necessary to prepare for the next phase of meiosis.

2. RNA synthesis:
RNA synthesis, also known as transcription, is a common event between interphase 1 and interkinesis. It takes place in both stages to produce RNA molecules necessary for cellular processes.

3. DNA synthesis:
DNA synthesis, or DNA replication, is specific to interphase 1. It occurs during the S phase of interphase 1, leading to the formation of sister chromatids.

4. Protein synthesis:
Protein synthesis, also known as translation, is a common event between interphase 1 and interkinesis. It involves the assembly of amino acids into proteins based on the instructions encoded in the RNA molecules.

Conclusion:
Among the events mentioned (growth in cell, RNA synthesis, DNA synthesis, and protein synthesis), the event that is not common between interphase 1 and interkinesis is DNA synthesis. DNA synthesis occurs only during interphase 1, specifically in the S phase, while interkinesis is a resting phase without DNA replication. The other events, such as growth in cell, RNA synthesis, and protein synthesis, are common between interphase 1 and interkinesis, as they are essential for cellular processes and growth during both stages of meiosis.
