Questions & Step-by-Step Solutions
In which phase of the cell cycle does DNA replication occur?
Correct Answer: S phase
Step 1: Understand that the cell cycle has different phases.
Step 2: Identify the phases of the cell cycle: G1, S, G2, and M.
Step 3: Know that 'S' stands for 'Synthesis'.
Step 4: Remember that DNA replication is the process of copying DNA.
Step 5: Conclude that DNA replication happens during the S phase.
Cell Cycle Phases – The cell cycle consists of several phases, including G1, S, G2, and M, with DNA replication specifically occurring in the S phase.
DNA Replication – DNA replication is the process by which a cell duplicates its DNA, ensuring that each daughter cell receives an identical set of chromosomes.
