Question

Which statement is incorrect for post mitotic gap phase of interphase?

• A. In this phase, cell is metabolically active and grows continuously.
• B. It involves replication of RNA, DNA and proteins.
• C. Cell organelles increase in number
• D. The cell has an option to stop cell cycle and undergo differentiation.

Answer 1

Answer: (B)

Interphase is the first growth stage after cell division. Three stages occur during interphase i.e.G1, S, and G2 stage wherein G1 stage cells mature by making more cytoplasm and cell organelles. S phase is called the post-mitotic gap phase and during that phase, the cell synthesizes enzyme and energy needed for DNA duplication. It occurs between the G1 and G2 phases of the interphase. In the G2 phase, all cell structures needed for cell division are made. Example: centriole. So the incorrect option is B.
