Mitosis

Definition

Mitosis is a type of cell division in eukaryotic cells where a single cell divides to produce two genetically identical daughter cells. It is essential for growth, development, and tissue repair.

5 Must Know Facts For Your Next Test

1. Mitosis consists of five stages: prophase, prometaphase, metaphase, anaphase, and telophase.
2. During mitosis, the chromosome number remains the same in the daughter cells as in the parent cell.
3. The spindle apparatus is crucial for separating chromosomes during mitosis.
4. Mitosis is distinct from meiosis, which results in four non-identical daughter cells with half the chromosome number of the parent.
5. Errors in mitosis can lead to conditions such as cancer due to uncontrolled cell division.
