  • Mutations are changes in genetic material – changes in DNA code – thus a change in a gene(s)
  • In gene mutations, the DNA code will have a base (or more) missing, added, or exchanged in a codon. (c) The mutation is a process that produces a gene or chromosome that differs from the wild type (arbitrary standard for what “normal” is for an organism). GENE MUTATIONRefers to thechange in the sequenceof nucleotide bases ofthe DNA that corresponds to a particular gene. An insertion changes the number of DNA bases in a gene by adding a piece of DNA.
