Which of the following statements are correct for G1 phase 1.it is the...
**Explanation:**
The correct option is b) 2 and 4. Let's understand why.
1. **It is the last substage of interphase:** This statement is incorrect. G1 phase is the first substage of interphase, not the last. Interphase consists of three subphases: G1, S, and G2. G1 phase is the initial phase where the cell prepares for DNA replication.
2. **Cell organelles do not increase in number:** This statement is correct. During G1 phase, the cell mainly focuses on cell growth and carrying out its specific functions. The organelles that are already present in the cell continue to function, but their number does not increase significantly during this phase.
3. **Both cell and nucleus grow in size:** This statement is incorrect. While the cell does grow in size during the G1 phase, the nucleus remains relatively constant in size. The nucleus will undergo growth and division during the subsequent phases of the cell cycle.
4. **It synthesizes RNAs, proteins, and other biochemicals for cell growth and subsequent replication of DNA:** This statement is correct. G1 phase is a critical period where the cell actively synthesizes RNA, proteins, and other biochemicals required for cellular growth and DNA replication. This phase prepares the cell for the S phase, where DNA synthesis occurs.
In summary, the correct statements for G1 phase are that cell organelles do not increase in number, and the phase is responsible for synthesizing RNAs, proteins, and other biochemicals for cell growth and subsequent replication of DNA.
