The correct answer to the question is:
c) Subtraction
Explanation:
1. Mutations are changes that occur in the DNA sequence. These changes can be categorized into different types such as insertion, deletion, and substitution.
2. Insertion refers to the addition of one or more nucleotide bases into the DNA sequence.
3. Deletion is the removal of one or more nucleotide bases from the DNA sequence.
4. Substitution involves the replacement of one nucleotide base with another in the DNA sequence.
5. However, "Subtraction" is not a recognized type of mutation in genetics. This option is incorrect as mutations typically involve additions, deletions, or substitutions of nucleotide bases in the DNA.
Therefore, in the context of genetic mutations, "Subtraction" does not represent a valid type of mutation.
