GENE MUTATION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A base-pair substitution that results in a codon that codes for a different amino acid.
A
non-sense mutation
B
silent mutation
C
missense mutation
D
deletion mutation
Explanation: 

Detailed explanation-1: -(MIS-sens myoo-TAY-shun) A genetic alteration in which a single base pair substitution alters the genetic code in a way that produces an amino acid that is different from the usual amino acid at that position. Some missense variants (or mutations) will alter the function of the protein. Also called missense variant.

Detailed explanation-2: -A point mutation that changes a codon specifying a different amino acid is called as missence mutation.

Detailed explanation-3: -Missense: A missense variant is a type of substitution in which the nucleotide change results in the replacement of one protein building block (amino acid) with another in the protein made from the gene.

Detailed explanation-4: -A nonsense mutation occurs in DNA when a sequence change gives rise to a stop codon rather than a codon specifying an amino acid.
