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. Nonsense mutation
B. Reverse mutation
C. Frame shift mutation
D. Mis-sence mutation

Answer

D

Explanation

Types of point mutation :
`**" "`Non-sence mutation : In this, mutation stops protein synthesis due to formation of non-sence or stop codon. E.g. : `U UA rarr UA A`.
`**" "`Mis-sence mutation : In this, mutation changes the codon that produces different amino acid e.g. : `U UA rarr U U U`.
`**" "`Same sence mutation : It is silent mutation in which codon is changed but amino acid is not change due to degeneracy. e.g.: `U UA rarr U UG`.
