The best response that describes the most likely impact of the mutation in the mutated sequence is:
The protein formed will not be the same as that formed from the original DNA sequence.
Mutations can change the nucleotide sequence, which may lead to a different amino acid being incorporated into the protein or cause a change in the reading frame, potentially altering the entire sequence of amino acids coded for after the mutation. This could result in a protein that is significantly different in structure and function compared to the original one.
