Question

mia is studying how cells prepare to divide. she wants to know during which part of the cell cycle dna replication takes place. can you help her?

Explanation:

Cell cycle has different phases. In the S - phase (Synthesis phase) of the cell cycle, DNA replication occurs. G1 is the gap 1 phase where the cell grows and prepares for DNA replication. G2 is the gap 2 phase where the cell prepares for mitosis. Mitosis is the phase of cell division where the cell divides into two daughter cells. Since the question is about when DNA replication takes place, we refer to the basic knowledge of cell cycle phases.

Answer:

DNA replication takes place during the S - phase.
