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

A substitution of a serine amino acid for a glycine amino acid
A substitution of glycine amino acid for a stop codon
An insertion or deletion of nucleotides that is not a multiple of three
A codon mutated from CCG to CCA, both coding for glycine

Answer 1

Answer:A substitution of glycine amino acid for a stop codon is an example of a nonsense mutation.

Step-by-step explanation:

A nonsense mutation is a type of point mutation that results in the formation of a premature stop codon in the mRNA sequence.

Answer 2

An insertion or deletion of nucleotides that is not a multiple of three
