Answer 1

I think the correct answer from the choices listed above is option C. The substitution, addition, or removal of a single nucleotide in DNA is called a point mutation. It is a type of mutation that affects only one or very few nucleotides in a gene sequence.

Answer 2

C (Point mutation)

Step-by-step explanation:

Mutation is any change, no matter the degree or size, that occurs in a nucleotide sequence of a DNA. It occurs naturally due to mistakes during replication or can be induced by mutagens (mutation-causing components). A mutation is regarded to be POINT MUTATION, if it affects only a single nucleotide in the sequence.

Point mutation occurs in scenarios whereby a single base pair/nucleotide is substituted/replaced, deleted/removed from the sequence, or inserted/added. This sorts of mutation can yield beneficial or harmful effect in the organisms they occur.
