WebThe cell cycle. In eukaryotic cells, the cell cycle is divided into two major phases: interphase and mitosis (or the mitotic (M) phase). Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells. WebYou have studied mitosis in onion root tip cells. It has 16 chromosomes in each cell. Can you tell: (i) How many chromosomes will the cell have at the G1 phase, after S phase, and after M phase? Q. During the study of mitosis in onion root tip cells, we found 16 chromosomes in each cell.
