The Cell Cycle

Ms. Addison

Interphase

  • The cell spends 90% of their time in interphase
  • Interphase consists of 3 different phases (G1,S,G2)
  • In Growth Phase 1 (G1) the cell grows
  • In the Synthesis Phase (S) DNA replicates
  • In Growth Phase 1 (G2) the cell prepares for mitosis

Prophase

Mitosis begins with prophase

Chromatin Condenses into chromosomes

The nucleus & nuclear membrane disappear

The centrioles move to opposite ends

Prophase: The First Stage of Mitosis

Metaphase

Chromosome pairs line up along the "middle" or "equator" of the cell

Anaphase

Chromosome separate into chromatids and the chromatids pull apart

Telophase

  • Two new nuclei (nucleus plural) form
  • Chromosomes change into chromatin
  • Mitosis ends with telophase

Cytokinesis

The cytoplasm separates into two. Two new cells form.
