Question

Mutations that result from the substitution of one nitrogen base for another are called deletions.

Select one:
True
False

Answer 1

Substitution of one nitrogen base for another in DNA is known as a substitution mutation, not a deletion mutation, which actually refers to the removal of nucleotides.

Step-by-step explanation:

The statement that mutations resulting from the substitution of one nitrogen base for another are called deletions is false. The correct term for the substitution of one nitrogen base for another in DNA is a substitution mutation. There are different types of substitution mutations, including transitions and transversions. On the other hand, a deletion mutation refers to the removal of one or more nucleotides from the DNA sequence, which can have a drastic effect on the resulting protein if it causes a frameshift.
