Question
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)
Responses

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

The mutated codon prevents the protein from forming and causes a disease.

Answer 1

The most likely effect of the mutation, given that the new codon codes for the same amino acid as the original codon, is:

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

This type of mutation is known as a "silent mutation," where a change in the DNA sequence does not lead to a change in the amino acid sequence of the protein. As a result, the overall function of the protein remains unchanged, and it is unlikely to cause disease.
