The correct answer should be - Substitution mutation.

A Substitution mutation is a kind of mutation that occurs in a DNA sequence where one base pair in the sequence is substituted with another pair of the nucleotide base pair.

There are 2 types of Substitution mutations - Transversion and Transition mutations.

In Transversion mutations, the purine in the sequence is replaced by a pyrimidine or a pyrimidine is replaced by a purine.

In a Transition mutation, one purine is replaced with another purine or a pyrimidine is replaced with another pyrimidine only.

Missense mutation is a change in one DNA base pair which results in the substitution of one amino acid for another in the protein made by a gene.


It is a mutation in which one DNA nucleotide is replaced by another one in such a way that it changes the amino acid specified. It changes one of the RNA codon sequences made during transcription, when it occurs in a DNA molecule.
