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.
