Mitosis


The Cell CYCLE consists of Interphase and MITOSIS (division of the nucleus). Most of the time the cell is in INTERPHASE as the cell prepares for division.

G1


INTERPHASE

  • The cell’s chemical machine operates and the cell grows (G1 phase).

  • The SYNTHESIS of DNA (S phase).

  • PREPARE for cell division


MITOSIS

1. The chromatin CONDENSES (shortens) into chromosomes.

Chromatin vs. Chromosomes

  • Long/thin

  • Invisible

  • Active

  • Working cell

  • Short/thick

  • Visible

  • Inactive

  • Dividing cell


  • The nuclear membrane and nucleolus DISAPPEAR.

  • Centrioles move apart to opposite ends of the cell.

  • SPINDLE fibers from the centrioles attach to centromeres.


Chromosomes


Metaphase

1. Chromosomes line up on the EQUATOR of the cell.


Anaphase

  • Centromere SPLITS.

  • Chromosomes are PULLED to the ends of the cell.


Telophase

  • Chromosomes ARE AT the ends of the cell.

  • Chromosomes DECONDENSE (lengthen) to form chromatin.

  • The nuclear membrane and nucleolus REAPPEAR.

  • The centrioles SEPARATE.

  • The CYTOPLASM is divided. (Cytokinesis)
