Mutations cause changes in the genetic code that lead to genetic variation and the potential to develop disease. Gene mutations can be generally categorized into two types: point mutations and base-pair insertions or deletions. Point mutations are the most common type of gene mutation. Also called a base-pair substitution, this type of mutation changes a single nucleotide base pair.
In genetics, the mutation rate is the frequency of new mutations in a single gene or organism over a various amount of time. Mutation rates are not constant and are not limited to a single type of mutation, therefore there are many different types of mutations. Mutation rates are given for specific classes of mutations. Point mutations, are a class of mutations, which are small or large scale insertions or deletions. There are also Missense and Nonsense mutations, which are variations of point m
