Questions & Step-by-Step Solutions

What phase of the cell cycle is characterized by DNA replication?
  • 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, including G1, S, G2, and M.
  • Step 3: Identify that the S phase stands for 'Synthesis' phase.
  • Step 4: Recognize that during the S phase, the cell makes a copy of its DNA.
  • Step 5: Conclude that DNA replication happens specifically in the S phase, leading to duplicated chromosomes.
