Introduction:

Mutations refer to the random alterations of the nucleotide-base sequence of the genome. These alterations can be caused by different agents or can occur due to spontaneous reasons; they are typically permanent in nature. A mutation not only changes the nucleotidebase sequence but also affects the overall gene expression. Based on the extent and nature of the change produced, mutations are classified into point, transition, transversion, silent, and missense mutations.
