Final answer:
Transfer RNA (tRNA) delivers the appropriate amino acids within the cytoplasm to their designated site at the ribosome.
Step-by-step explanation:
Transfer RNA (tRNA) is a type of RNA that delivers the appropriate amino acids within the cytoplasm to their designated site at the ribosome. Each tRNA molecule carries a specific amino acid and recognizes the codons on the mRNA that define the order of amino acids in a protein. Equipped with its particular cargo and matching anticodon, a tRNA molecule can read its recognized mRNA codon and bring the corresponding amino acid to the growing chain.
