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.
A mutation is simply a change in your genes or DNA sequence. The types of mutations in biology are: substitution, insertion, deletion, and frame-shift. Contrary â¦ to popular belief, mutations are often harmless.
