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
Answer is C. C i.e. Reading frame changes down stream to the mutant site
