Some aminoacyl-tRNA synthetases do not recognize and bind the anticodon of their cognate tRNAs, but instead use other structural features of the tRNAs to impart binding specificity. Alanine-tRNA synthetase falls into this category. Describe the consequences of a Cā G mutation in the third position (3'-end) of the anticodon in tRNAAla?
a. The consequences would be the insertion of Pro for Ala in proteins.
b. The consequences would be the insertion of Ala for Pro in proteins.
c. Protein synthesis would not initiate because of the mutation of the start codon.
d. Many shortened proteins would be produced because termination codons could replace Pro codons.
e. Many shortened proteins would be produced because termination codons could replace Ala codons.
