Study Notes

Cell Division

  • A process where a cell divides to create two new cells.
  • Crucial for growth, development, tissue repair, and reproduction.
  • Helps in material exchange and prevents DNA overload.

Types of Cell Division

  • Prokaryotes (Bacteria)
    • Binary Fission: Divides into two identical cells.
  • Eukaryotes
    • Mitosis: Used for growth and repair.
    • Meiosis: Produces sex cells or gametes.

Prokaryotic Cell Division: Binary Fission

  • DNA Replication: DNA copies to form two identical chromosomes.
  • Chromosome Segregation: Chromosomes move to opposite ends of the cell.
  • Cytokinesis: Cytoplasm splits, resulting in two daughter cells.
  • Daughter cells are genetically identical to the parent cell.

Eukaryotic Cell Division: Mitosis

  • Results in two daughter cells with the same chromosome number and type as the parent.
  • Steps of Mitosis:
    • Prophase: Chromosomes condense and nuclear envelope breaks down.
    • Metaphase: Chromosomes align at the cell's equator.
    • Anaphase: Sister chromatids separate and move to poles.
    • Telophase: Nuclear envelope reforms around separated chromosomes.
  • Cytokinesis: Cytoplasm divides to form two new daughter cells.

The Cell Cycle

  • Sequence from cell formation to cell division.
  • Composed of growth, DNA replication, and preparation for division.
  • Divided into two main periods:
    • Interphase
    • Mitotic Phase

Interphase

  • A growth and DNA replication stage between divisions.
  • Phases of Interphase:
    • G1 Phase: Cell increases in size.
    • S Phase: DNA replication occurs, forming sister chromatids.
    • G2 Phase: Organelles double, cytoplasm increases, and structures needed for mitosis are prepared.

Mitotic Phase

  • The stage where cell division occurs.
  • Mitosis: Division of the nucleus into two genetically identical daughter nuclei.
  • Involves two processes:
    • Nucleus division
    • Separation of cytoplasm into daughter cells.
  • Divided into:
    • First Mitotic Phase: Mitosis (Prophase > Metaphase > Anaphase > Telophase)
    • Second Mitotic Phase: Cytokinesis.
