Question

Cells pass through a G2 checkpoint before entering mitosis. Ideally, if DNA damage is 2 detected, the cells do not enter mitosis until the damage is repaired. Why is DNA damage repaired before cells enter mitosis? *
A.) So that another round of DNA synthesis does not have to take place

B.) So that the chromosomes can align at the metaphase plate during mitosis

C.) So that the cytoplasm can be divided equally between the two daughter cells

D.)So that healthy daughter cells are produced, allowing the organism to continue growing

Answer 1

I think that the answer is D. The cell employs the G2 checkpoint to check for DNA damage and completeness of DNA replication. This is done to ensure that cell division runs smoothly which means that healthy daughter cells, with complete and undamaged DNA, will be produced. At this point, all necessary repairs are applied.
