3.24 a Mitosis

Key points:
1. Mitosis is a form of cell division which results in growth. Increase in number of cells.
2. A normal cell has a nucleus, and the number of chromosomes in there is known as the diploid number, or substituted as 2n. For humans, 2n = 46, for cats 2n = 38.
3. During mitosis, a cell will divide into two cells, each with a nucleus. Inside the nucleus of each one you'll find it has a diploid nucleus. These cells are identical, or daughter cells. They are identical in 2 ways. They have the same number of chromosomes, and the second is that they have the same set of chromosomes.
4. This means that one chromosome in one cell is identical to the same version on it in the other cell.
