Question

A point mutation changes the DNA sequence CGA to CGT, but the same protein is still produced. Which point mutation occurred?

Answer 1

If there is a change in a single nucleotide and  even after the change the amino acid is coding for the same protein this term is called as silent mutation

Point mutation has 3 types :

• nonsense

•  missense

• silent

Silent mutation is a part of point mutation in which two amino acids codes for the same protein so there is no difference in the protein formed but the sequence changes.
