KEY FACTS
 
  • Mitosis is a type of cell division. When body cells divide to increase their number, or an organism reproduces asexually, cell division occurs by mitosis.
  • The cell's DNA is replicated in mitosis and each new cell produced receives an exact copy of the DNA in the parent cell.
  • Replication of the DNA in the chromosomes occurs during interphase before the chromosomes contract and become visible in the nucleus.
  • Replication produces two identical chromatids from each chromosome. The chromatids are separated during mitosis in a process that guarantees that each daughter nucleus has one of each pair.
