m_a_m_a [10]

Phase of the cell cycle in which cells grow, duplicate organelles, and synthesize DNA.

S phase

Explanation:

 DNA replication occurs in synthesis or in the S phase of the cell cycle. Each chromosome is copied with high fidelity in a process that involves a large number of enzymes. In this process the double strand of DNA breaks down and each individual strand is used as a template for the production of the complementary one. The result is the production of two identical copies of the genetic material.
