Chemical conversion of the cysteine residue in cys-tRNAcys to alanine, to yield ala-tRNAcys, results in:
A) . a change in reading frame of the mRNA because of failure of the amino acid to match its codon.
B) incorporation of ala residues in proteins where cys was encoded.
C) incorporation of cys residues in proteins where ala was encoded.
D) premature termination at the site where the first cys was encoded.
E) utilization of an alternate cys-tRNA, available because of the degeneracy of the code.
