  • Process of a cell dividing
    1. Interphase: The cells prepare for division by growing and replicating its DNA
    2. Prophase: Chromatin condenses into chromosomes and the nuclear membrane dissolves
    3. Metaphase: Chromosomes line up along the centre of the cells
    4. Anaphase: Chromatids separate and move at opposite ends of the cells
    5. Telophase: Chromatids reach the poles and new nuclear membranes form around them
    6. Cytokinesis: The cell divides into two daughter cells, each with a complete set of chromosomes
  • Summary of Genetics

    • Chromosomes are found in the nucleus
    • Chromosomes come in pairs
    • Chromosomes contain genes
    • Humans contain 46 chromosomes in their body cells
    • Chromosomes in humans have 23 pairs
    • Males have 22 pairs + sex chromosomes ( X and Y )
    • Females have 22 pairs + sex chromosomes ( X and Y )
  • DNA

    Deoxyribonucleic acid, made up of bases of which there are 4: Adenine, Thymine, Guanine and Cytosine
  • Extra chromosomes can cause genetic difficulties, e.g Down Syndrome
