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.
© 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 specific checkpoints (such as the G1, G2, and M checkpoints) that monitor the integrity of the genetic material. If errors or damage are detected, the cell can halt the cycle to allow for repair mechanisms to fix the errors before the cell proceeds to divide. This helps to maintain genetic stability and prevent the propagation of mutations.
