Answer 2

The correct answer is A. deletion.

Explanation:

• Mutation can be defined as an alteration in the sequence of the DNA.
• This can be caused due to the inaccurate copying of the DNA sequence by the DNA polymerase at the time of replication.
• This can also be caused by exposure to environmental mutagens like ultraviolet (UV) rays.
• If this DNA is a part of a protein coding gene, then due to the deletion of a single nucleotide in the DNA sequence it can result into a protein with altered amino acid sequence, which most probably, lack the required function.
