- 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.

Few mutations result in new versions of proteins and help the organisms to adapt to changes in the environment. Change in a single nucleotide base pair. mutations are silent because the encoded amino acid remains the same or the amino acid substitution is sufficiently subtle so as not to compromise activity of the enzyme. Types of Gene Mutations :Types of Gene Mutations Include: Point Mutations … This point mutation changes the meaning, resulting in nonsense.
