  process of mitosis.
• Prophase
• Metaphase
• Anaphase
• Telophase

What are chromosomes?

• When there are 2 sets of DNA in the nucleus, the
  chromatin will begin to condense into
  chromosomes.
• The chromatid is half of the chromosome(X)

Prophase

• Chromatin condenses (shrivel/bunch up) to form
  chromosomes
• Spindle fibers appear

5
Metaphase

• Chromosomes line up in the middle
• Spindle fibers are very evident

6
Anaphase

• Spindle fibers pull apart the chromosomes so that
  half (chromatid) goes to each side.

7
Telophase

• Cell membrane begins to form between the 2 nuclei
• The chromosomes begin to loosen up into
  chromatin.

Result of Mitosis

• When mitosis is complete, you end up with 1 cell
  but it has 2 nuclei.
