The correct Answer is:
To solve the question regarding the incorrect statement for the post mitotic gap phase of interphase (G1 phase), we will analyze each option provided. ### Step-by-Step Solution: 1. **Understanding the G1 Phase**: - The post mitotic gap phase, also known as the G1 phase, is the first phase of interphase that occurs after mitosis. During this phase, the cell prepares for DNA replication. 2. **Analyzing Option (a)**: - **Statement**: "In this phase, the cell is metabolically active and grows continuously." - **Analysis**: This statement is true. The G1 phase is characterized by active metabolism and cell growth. 3. **Analyzing Option (b)**: - **Statement**: "It involves replication of RNA, DNA, and proteins." - **Analysis**: This statement is incorrect. While RNA and proteins are synthesized during the G1 phase, DNA replication occurs in the S phase, not in G1. Therefore, this statement is false. 4. **Analyzing Option (c)**: - **Statement**: "Cell organelles increase in number." - **Analysis**: This statement is true. During the G1 phase, the cell organelles duplicate, preparing for cell division. 5. **Analyzing Option (d)**: - **Statement**: "The cell has an option to stop the cell cycle and undergo differentiation." - **Analysis**: This statement is also true. Cells can exit the cell cycle and enter a quiescent state (G0 phase) during G1, allowing for differentiation. ### Conclusion: After analyzing all the options, the incorrect statement regarding the post mitotic gap phase of interphase is **(b)**: "It involves replication of RNA, DNA, and proteins."
