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.
Types of Mutations - Frameshift, Chromosomal and Point Mutation. Article Summary: Mutations are the changes in the structure of the DNA molecule or the changes in the gene sequences. There are many types of mutations which cause the defect in the genetic information.... When the DNA molecule in the cell replicates, several chemical changes occur during this process.
