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)
1The mutated codon produces the same protein as the original codon and
does not cause a disease.
2The 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.
3The mutated codon prevents the protein from forming and causes a
disease.
4The mutated codon produces a different protein than the original codon
and causes a disease because the protein does not function properly.
