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.
Point mutations are the most common type of mutation. A single point mutation, also called a base substitution, occurs when a. single nucleotide is replaced with a different nucleotide. A point mutation results in a base pair substitution after replication and. possibly a mutant protein after transcription and translation.
