Which Of The Following Statements Correctly Describes The Timing Of DNA Synthesis?

Answer: DNA synthesis, also known as DNA replication, occurs during the S phase (Synthesis phase) of the cell cycle. The cell cycle consists of several phases:

  1. G1 Phase (Gap 1): The cell grows and carries out normal functions.
  2. S Phase (Synthesis): DNA is replicated during this phase. Each chromosome duplicates to form two sister chromatids connected by a centromere.
  3. G2 Phase (Gap 2): The cell continues to grow and prepares for mitosis.
  4. M Phase (Mitosis): The cell divides into two daughter cells.

Summary: DNA synthesis takes place during the S phase of the cell cycle, which is crucial for cell division as it ensures each daughter cell receives an identical copy of the DNA.
