transfer rna (trna) is the rna molecule that
provides a work bench to carry out protein synthesis
transfers a specific amino acid to the ribosome to build the polypeptide chain
carries the instructions for building genes (proteins)
provides a coded message to be translated into a polypeptide chain

Explanation:

Transfer RNA (tRNA) has an anticodon that pairs with a codon on mRNA and carries a specific amino - acid to the ribosome for polypeptide chain synthesis during translation. The workbench for protein synthesis is the ribosome (not tRNA), the instructions for building proteins are carried by messenger RNA (mRNA), and the coded message for translation into a polypeptide chain is also on mRNA.

Answer:

B. transfers a specific amino acid to the ribosome to build the polypeptide chain
