Question

Transfer RNA __________. A is translated into protein B tags a growing polypeptide for export to the endoplasmic reticulum C is produced in the nucleolus D has catalytic activity and is thus a ribozyme E binds to its specific amino acid in the active site of an aminoacyl-tRNA synthetase

Answer 1

The answer is E. The function of t RNA is to transfer aminoacids into ribosomes for protein synthesis. Aminoacyl-tRNA synthetase is the enzyme that binds the related aminoacids into trna for transfer. What determines which aminoacids will be transferred into ribosomes is the codons on mRNA.
