  • Point mutations – mutations where one letter changes on the DNA sequence.
  • Inversion mutations – a segment of DNA in a particular strand that reverses itself
  • Insertion mutations – a segment of DNA, whether a single base pair or an extensive length, that is inserted into the DNA strand.
  • Deletion mutations – a segment of DNA, whether a single base pair or an extensive length, that is deleted from the strand.
  • Frame shift mutations – These mutations can be caused by an insertion or deletion of one or more letters not divisible by three, which causes an offset in the reading of the “letters” of the DNA.
