3.24b Mitosis

Understand that division of a diploid cell by mitosis produces two cells which contain identical sets of chromosomes.

Interphase Cycle

  1. Parent cell.
  2. Chromosomes make identical copies of themselves.
  3. They line up along the center.
  4. They move apart.
  5. Two daughter cells form with identical chromosomes to the parent cell.
    This is called DNA replication.

    What holds the 2 resulting copies together is the "centromere." It is located in the middle of the chromosomes.
    When like this, they are referred a "pair of chromotids."
