Three different types of excision repair have been characterized: nucleotide excision repair, base excision repair, and mismatch repair.
WebDuring interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells. Interphase Let’s enter the cell cycle just as a cell forms, by division of its mother cell. The centrosomes migrate to the opposite ends of the cell. And our DNA … Prior to S-phase each chromosome is a single chromatin fiber.
