Question

4 cells pass through a g₂ checkpoint before entering mitosis. ideally, if dna damage is 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

Explanation:

DNA is the genetic material. If damaged DNA is passed on during mitosis, daughter - cells will have genetic errors. Repairing DNA before mitosis ensures the production of healthy daughter - cells which is crucial for the organism's growth and proper functioning. Options A, B, and C are not the main reasons for DNA repair before mitosis. Option A is about DNA synthesis which is not the main concern here. Option B is about chromosome alignment which is not directly related to DNA repair. Option C is about cytoplasm division and not about DNA integrity.

Answer:

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