Which type of ribonucleic acid (rna) is responsible for delivery of appropriate amino acids within the cytoplasm to their designated site in the protein under construction?

Transfer RNA (tRNA) is a type of RNA that ferries the appropriate corresponding amino acids to the ribosome, and attaches each new amino acid to the last, building the polypeptide chain one-by-one. Thus tRNA transfers specific amino acids from the cytoplasm to a growing polypeptide.
