Question

during the process of translation, what is the primary function of a transfer rna (trna) molecule?
to carry the genetic instructions from the dna in the nucleus to the cytoplasm.
to bind to a specific amino acid and deliver it to the ribosome for polypeptide synthesis.
to catalyze the formation of peptide bonds between amino acids.

Explanation:

Transfer RNA (tRNA) has an anticodon that pairs with the codon on mRNA and a binding - site for a specific amino - acid. It brings the amino - acid to the ribosome for polypeptide synthesis during translation. Carrying genetic instructions from DNA to cytoplasm is the function of mRNA, and ribosomal RNA (rRNA) is involved in catalyzing peptide bond formation.

Answer:

To bind to a specific amino acid and deliver it to the ribosome for polypeptide synthesis.
