CHROMOSOMES, GENES & DNA - Coggle Diagram

- - - - The sequence that codes all the amino acids is called a gene.
- - - - A sugar molecule (deoxyribrose)
      - A phosphate group
      - Nitrogen-containing group (Base)
        
        Thymine (T)
        
        Cytosine (C)
        
        Guanine (G)
        
        Adenine (A)
- - - - Ionising radiation (UV light, X-rays, and gamma rays)
      - Various chemicals (mustard gas, nitrous oxide, cigarette smoke, etc)
    - - Deletion: a nucleotide will be missing out and the mutation needs to code for an entirely different protein
      - Substitution: When a different nucleotide is being used.
      - Inversion: When the sequence in a triplet is reversed.
      - Duplication: the nucleotides is inserted twice rather than just once so the mutation needs to be altered
