Question

during which occasion would dna replication occur?
a. a cell is preparing to undergo cytokinesis.
b. a cell is synthesizing proteins.
c. a cell is preparing to undergo mitosis.
d. a cell is undergoing cellular respiration.

Explanation:

DNA replication occurs during the S - phase of the cell cycle, which is part of the interphase before mitosis. Mitosis is the process of cell division, and for a cell to divide properly (mitosis), it needs to replicate its DNA first so that each daughter cell gets a complete set of genetic material. Cytokinesis is the division of the cytoplasm (occurs after mitosis), protein synthesis is mainly in the G1 and G2 phases (not directly related to DNA replication in terms of the key event here), and cellular respiration is about energy production (not DNA replication).

Answer:

C. A cell is preparing to undergo mitosis.
