A DNA codon that codes for a certain protein undergoes a substitution mutation. The new codon codes for the same amino acid as the original codon. What is the most likely effect of the mutation?(1 point)

Question

Responses

The mutated codon prevents the protein from forming and causes a disease.
The mutated codon prevents the protein from forming and causes a disease. - no response given

The mutated codon produces a protein with the same amino acid sequence as the original codon and causes a disease because the protein does not function properly.

The mutated codon produces a different protein than the original codon and causes a disease because the protein does not function properly.

Answer 1

The correct response is:

The mutated codon produces the same protein as the original codon and does not cause a disease.

This is because the mutation is a substitution that results in a codon coding for the same amino acid, which is known as a silent mutation. Silent mutations usually do not affect the function of the protein and therefore are unlikely to cause disease.
