When examining cells in the laboratory, you notice that a particular cell has half as much DNA as the surrounding cells. This observation can be explained if this cell's cell cycle halted at checkpoint _____.

Answer:

G1

Explanation:

The cell cycle is divided into 2 main phases namely:

  • The interphase
  • The m phase

While the m phase is the active division phase, the interphase is further divided into:

  • G0 phase which is essentially a resting or quiescence phase for cells that do not need to divide ordinarily.
  • G1 phase which is characterized by growth and development of the cell.
  • S phase which is a phase during which DNA is synthesized
  • G2 phase during which protein is synthesized.

Hence, if a cell is noticed to have half as much DNA as the surrounding cells, it means that particular cell's cell cycle halted at G1. The cell has not been able to synthesize DNA unlike the surround cells.
