Chromosomes and cell division

WebThere are two ways cell division can happen in humans and most other animals, called mitosis and meiosis. When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides by way of meiosis, it … 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. …
