During ______, the cell duplicates its contents, including its DNA. Multiple choice question.prophaseinterphasemetaphasetelophase

The correct answer is interphase.

Explanation

Interphase is the phase in the cell cycle where the cell prepares for division. It occurs before mitosis or meiosis and consists of three main stages: G1 (first gap), S (synthesis), and G2 (second gap). During the S phase, the cell duplicates its DNA, ensuring that each daughter cell will receive an identical copy of the genetic material upon cell division. This is crucial for maintaining the integrity of the genetic information as it ensures that all resulting cells will function properly and carry the same chromosomal content as the original cell.

In contrast, prophase, metaphase, and telophase are all stages of mitosis where the cell's replicated DNA is separated and distributed into daughter cells, rather than duplicating it.
