how mutations affect gene function
... Missense mutation: changes an amino acid to another amino acid. This may or may not affect protein function, depending on whether the change is “conservative” or “nonconservative,” and what the amino acid actually does. Nonsense mutation: changes an amino acid to a STOP codon, resulting in prematur ...

Point mutation

A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
