WebThe cell cycle is controlled at three checkpoints. The integrity of the DNA is assessed at the G 1 checkpoint. Proper chromosome duplication is assessed at the G 2 checkpoint. Attachment of each kinetochore to a spindle fiber is assessed at the M checkpoint. 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.
