Study Notes

Cell Division

  • Cell division promotes growth in organisms and facilitates repair by producing new cells to replace damaged ones.
  • Functions of cell division: repair and growth.

Overview of Mitosis

  • Mitosis results in the formation of daughter cells, which are identical to the original cell.
  • The cell cycle mainly includes three stages: interphase, mitosis, and cytokinesis.

Interphase

  • Interphase comprises approximately 90% of the cell cycle, where DNA is replicated and chromatin is formed from DNA and proteins.

Phases of Mitosis (PMAT)

  • Phases include:
    • Prophase
    • Metaphase
    • Anaphase
    • Telophase

Cytokinesis

  • Cytokinesis initiates during mitosis but ensures each daughter cell has the same number of chromosomes (46).
  • In animal cells, cytokinesis occurs through the cell membrane pinching inwards.
  • In plant cells, a cell plate forms instead of the cell pinching.

Chromosomes

  • Human cells contain 46 chromosomes within each nucleus.
  • Chromosomes consist of DNA and proteins.

Mitosis and Cell Types

  • Mitosis occurs in body cells. Sex cells, however, do not undergo mitosis.
