Mutation is generally defined as a sudden change to the DNA sequence of a cell. This change could be of difference forms, including:
- <em>Addition of bases</em>
- <em>Deletion of bases</em>
- <em>Substitution of bases</em>
<u>Addition of bases to a DNA will generally lead to a longer base pairs in the DNA, deletion will lead to a shorter base pairs while substitution will only lead to a change in the base sequence without any change in the length of the DNA.</u>
