Biochemistry Base substitution mutations can have be following molecular consequence except: A Changes one codon for an amino acid into another codon for that same amino acid B Codon for one amino acid is changed into a codon of another amino acid C Reading frame changes downstream to the mutant site D Codon for one amino acid is changed into a translation termination codon 💡 Explanation Base substitution mutations can have be following molecular consequence except: ✓ Correct Answer: C. Reading frame changes downstream to the mutant site
