Question

amino acids are in the correct order at the ribosome because _______. each trna has an anti - codon that is complementary (matches) to the mrna codon each amino acid can only stick to one other kind of amino acid

Explanation:

In protein - synthesis at the ribosome, tRNA molecules carry amino acids. The anti - codon on tRNA pairs with the mRNA codon through base - pairing rules. This ensures the correct order of amino acids in the growing polypeptide chain. Amino acids do not bond in a way that each can only stick to one other kind in the context of ribosomal protein synthesis.

Answer:

each tRNA has an anti - codon that is complementary (matches) to the mRNA codon
