Question

multiple choice question
which occurs during the s stage of interphase?

a cell grows, carries out normal cell functions,and prepares to replicate dna.
a cell prepares for the division of its nucleus and takes inventory to make sure
it is ready to continue with mitosis.
a cell copies its dna in preparation for cell division.

Explanation:

1. Analyze Option A: The description of a cell growing, carrying out normal functions, and preparing to replicate DNA is characteristic of the G₁ phase of interphase, not the S stage.
2. Analyze Option B: The process of a cell preparing for nuclear division and checking readiness for mitosis is part of the G₂ phase of interphase, not the S stage.
3. Analyze Option C: The S (synthesis) stage of interphase is defined by the cell copying its DNA (DNA replication) in preparation for cell division (either mitosis or meiosis). This matches the definition of the S stage.

Answer:

C. A cell copies its DNA in preparation for cell division.
