The DNA replication occurs during the S phase of the cell cycle.
Explicación
## Step 1The cell cycle is a series of events that cells undergo as they divide and grow. It consists of four main phases: G1, S, G2, and M. ## Step 2During the G1 phase, the cell grows and prepares for DNA replication. This phase is characterized by the cell's growth and the synthesis of proteins necessary for DNA replication.## Step 3The S phase, or synthesis phase, is the phase where DNA replication occurs. During this phase, each chromosome is replicated to produce two identical copies, known as sister chromatids.## Step 4The G2 phase is a period of growth and preparation for mitosis, where the cell checks the DNA for any errors and repairs them if necessary.## Step 5The M phase, or mitosis, is the phase where the cell divides its DNA and cytoplasm to produce two daughter cells.
