Question

Which of the following is an example of a frameshift mutation?

a deletion of a codon
missense mutation
silent mutation
deletion of one nucleotide

Answer 1

d

Step-by-step explanation:

Answer 2

-deletion of one nucleotide

Step-by-step explanation:

Frameshift mutations can be defined as mutations that lead to change the reading frame due to change in codon sequence of a gene. These mutations can be caused by addition or deletion of one or more (but not 3 or divisible by three) nucleotides from a gene.

As codons are made up of three nucleotides, due to deletion or addition codon sequence gets changed and makes a completely different gene product.

Thus, the correct answer is 'last option.'
