Question

Assertion (A): Cell growth is a continuous process in terms of cytoplasmic increase.

Reason (R): DNA synthesis occurs only during two specific stages in the cell cycle.

Options

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is true but R is false.

Explanation:

The assertion is true because cellular growth (cytoplasmic increase) is a continuous process that takes place steadily throughout the G₁, S, and G₂ phases of interphase. However, the reason is false because DNA synthesis is highly restricted and occurs during only one specific stage of the cell cycle, the S (Synthesis) phase, rather than two stages.
