Questions & Step-by-Step Solutions

Which phase of the cell cycle does DNA replication occur?
  • Step 1: Understand that the cell cycle is the process that cells go through to grow and divide.
  • Step 2: Learn that the cell cycle has different phases: G1, S, G2, and M.
  • Step 3: Identify that the S phase stands for 'Synthesis' phase.
  • Step 4: Know that during the S phase, the cell makes a copy of its DNA.
  • Step 5: Conclude that DNA replication specifically happens in the S phase of the cell cycle.
