Some aminoacyl tRNA synthetases do not recognize and bind

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 The tRNAs for alanine apparently fall into this category Ala What feature of tRNA does Ala tRNA synthetase recognize the acceptor stem and anticodon loop 3 70 G U base pair in the acceptor stem Darm TYC arm Ala What is the consequence of a C G mutation in the third position of the anticodon of tRNA Alanine inserts at codons encoding proline No changes occur because the anticodon does not specify alanine binding Proline inserts at codons encoding alanine No changes occur due to the wobble effect
