Answer 1

Answer:

B

Explanation:

Transfer RNA (tRNA) is an RNA molecule involved in the process of translation by which cells synthesize proteins. These molecules (tRNAs) have 76-90 nucleotides in length which form characteristic stem-loop structures, and they are considered adaptor molecules because tRNAs serve as the physical link between the messenger RNA (mRNA) and specific amino acid residues of the growing polypeptide chain. A tRNA is composed of a trinucleotide region (i.e., the anticodon region) that binds to the codon in the mRNA, and a region that attaches to a specific amino acid in order to transfer it to the ribosome, where protein synthesis takes place.
