Alteration of the sequence of bases in DNA
- FRAME-SHIFT
  - ADDITION
    - The addition of a base will shift the bases right, causing them to be read wrong
  - DELETION
    - The removal of a base, causing the bases to shift left
- SUBSTITUTION
  - Where one base is changed for another
- INVERSION
  - Where a section of bases breaks off and rearranges itself the wrong way
- DUPLICATION
  - One or more copies of a gene being made
- TRANSLOCATION
  - When part of a chromosome breaks off and attaches to a different chromosome
