Question

When a DNA sequence is being replicated, a cytosine base is replaced by a thymine base. This results in one wrong amino acid being attached to a protein during translation. What type of mutation is described?(1 point) Responses Deletion Deletion Inversion Inversion Substitution Substitution Insertion

Answer 1

The mutation described is a **substitution mutation**. This type of mutation occurs when one base pair in the DNA sequence is replaced by another, which is what happened when a cytosine (C) was replaced by a thymine (T). This can lead to a different amino acid being incorporated into the resulting protein during translation.
