Question

When a single nucleotide base pair is substituted, type of mutation occurs is?

Answer 1

A substitution is a mutation that exchanges one base for another (i.e., a change in a single "chemical letter" such as switching an A to a G). Such a substitution could: change a codon to one that encodes a different amino acid and cause a small change in the protein produced.

Answer 2

This type of mutation is called point mutation , but if nucleotide added or deleted then it’s called the frame shift mutation , example of the point shift mutation is sickle cell anaemia
