One action of tRNA (transfer RNA) molecules during translation is delivering amino acids to the ribosome.
tRNA acts as an adapter molecule that carries a specific amino acid to the ribosome, where it aligns with the complementary mRNA (messenger RNA) codon through its anticodon sequence.
This ensures the correct incorporation of the amino acid into the growing polypeptide chain. The specificity between the tRNA anticodon and the mRNA codon allows for accurate translation of the genetic code, enabling the synthesis of proteins with the correct sequence of amino acids.
Overall, tRNA plays a crucial role in the precise and controlled assembly of proteins during translation.
