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? so that another round of dna synthesis does not have to take place so that the chromosomes can align at the metaphase plate during mitosis so that the cytoplasm can be divided equally between the two daughter cells so that healthy daughter cells are produced, allowing the organism to continue growing
