- - - - Nucleotides
        
        Phosphate group
        
        Pentose sugar
        
        Ribose sugar (RNA)
        
        Deoxyribose sugar (DNA)
        
        Nitrogenous base
        
        Thymine
        
        Adenine
        
        Cytosine
        
        Guanine
        
        Uracil (replaces T)
      - Histone protein
        
        Used in gene expression (differentiation)
  - - - 46 single-strand chromosomes
    - - 46 double-strand chromosomes, 92 single-strand chromatids
    - - Prophase
        
        Chromatin condenses into chromosomes
        
        Nuclear membrane breaks down
        
        Spindle apparatus begins to form
        
        Formed by Centrioles
        
        which are 2 centrosomes
      - Metaphase
        
        Chromosomes line up in middle of the cell
        
        Spindle fibres form from both and attach to centromeres of chromatids
      - Anaphase
        
        Centromere proteins cleaved, sister chromatids seperated, pulled apart by spindle fibre contration to opposite sides of cell
      - Telophase
        
        Spindle fibres break down
        
        Nueclear membrane reforms to form 2 daughter nuceli
      - Meisos
        
        Literally the same thing, but two steps, and pairs of homologous chromosomes for Meisos I
      - Mitotic index
      - Telomere
    - - 46 single-strand chromosomes
