Solution

Cell cycle:

  1. An animal cell's cell cycle is divided into two stages: the Interphase and the M phase.
  2. During interphase, DNA is synthesized.
  3. Interphase is a preliminary phase that is separated into three parts: Gap1 (G1), Synthesis (S), and Gap2 (G2).
  4. True cell division occurs during the M phase of mitosis.

S phase :

  1. The replication phase is known as the S phase.
  2. DNA replication consumes the majority of the cell's resources.
  3. All 46 chromosomes are duplicated in human cells.
  4. Special proteins link the original and replicated chromosomes at a region known as the centromere.
  5. The cell has 92 chromatids at this point i.e. 42 original chromatids and 42 replicated chromatids.
