A mutation at one base of the first codon of a gene produces a non-functional protein. Such a mutation is referred as

Options

A. frameshift mutation
B. mis-sense mutation
C. non-sense mutation
D. reverse mutation

Answer

B

Explanation

If mutation at one base of the first codon of a gene takes place then all the subsequent codons will be out of register (genetic code). This results into the formation of mis-sense protein which is formed due to the mutation in the first base of first codon and thus called missense mutation.
