Question

When energy is stored and cell undergoes differentiation in adverse condition, the stage is called as

• A. Anaphase
• B. G${}_o$
• C. S
• D. G${}_1$

Answer 1

The correct option is B G${}_o$

The typical cell cycle comprises of interphase and mitotic phase (M phase). The interphase is divided into first growth phase (G${}_1$ phase), synthesis phase (S phase) and second growth phase (G${}_2$ phase). The DNA replication occurs during synthesis or S phase. Non-proliferative cells in multicellular eukaryotes generally enter the quiescent G${}_o$ state from G${}_1$ and may remain quiescent for long periods of time. Therefore, G${}_o$ is also called as a differential stage during which some cells enter permanent differentiation. Thus, the correct answer is option B.
