A mutation at one base of the first codon of a gene produces a non-functional protein. Such a mutation is referred asA. Nonsense mutationB. Reverse mutationC. Frame shift mutationD. Mis-sence mutation |

Answer» Correct Answer - D 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`. |
