GENE MUTATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A point substitution can result in all of the following except ____
A
Missense mutation
B
Frameshift Mutation
C
Silent Mutation
D
Nonsense mutation
Explanation: 

Detailed explanation-1: -They can arise from extremely simple mutations such as the addition or removal of a single nucleotide. Frameshift mutations do not include substitutions where a nucleotide replaces another. In substitution mutations, the polypeptide only changes by a single amino acid.

Detailed explanation-2: -So the correct answer is ‘Either an insertion or a deletion of a base’.

Detailed explanation-3: -A frameshift mutation is an insertion or deletion of a nucleotide base that changes the reading frame. A point mutation does not change the frame and only changes one amino acids.
