how are errors in the duplication of genetic material prevented during the cell cycle

Question

a. molecules of ATP provide the energy needed to remove errors from genetic material.
b. there are checkpoints where errors in genetic material are identified and removed
c. a phospholipid bilayer prevents errors in genetic material.
d. a concentration gradient is used to remove errors by passive transport

Answer 1

The correct answer is: b. there are checkpoints where errors in genetic material are identified and removed.

During the cell cycle, there are several checkpoints (such as the G1, G2, and M checkpoints) that monitor the integrity of the genetic material. If errors or damage are detected, mechanisms are activated to repair them or, if the damage is too severe, to induce apoptosis (programmed cell death) to prevent the propagation of errors.
