Final answer:
Hydrogen bonds mediate the interaction between tRNA nucleotide triplets and mRNA codons during protein synthesis, leading to the correct placement of amino acids. option b is correct.
Step-by-step explanation:
The interaction between the nucleotide triplets on tRNA molecules and triplet codons is mediated by hydrogen bonds. During the process of translation in protein synthesis, tRNA molecules carry amino acids to the ribosome. Here, the anticodon of a tRNA molecule forms hydrogen bonds with the complementary codon on the mRNA strand. This base-pairing is crucial for the correct placement of amino acids in the growing polypeptide chain. The formation of a peptide bond is a separate process that occurs between the amino acids as they are joined together to create a protein.
The interaction between the nucleotide triplets on tRNA (transfer RNA) molecules and triplet codons on mRNA (messenger RNA) during protein synthesis is mediated by hydrogen bonds. tRNA contains anticodons, which are complementary to the mRNA codons.
The specificity of base pairing, facilitated by hydrogen bonds, ensures accurate translation of the genetic code. The codon-anticodon recognition is crucial for bringing the correct amino acid to the growing polypeptide chain on the ribosome. This process, governed by hydrogen bonds, is essential for the fidelity and precision of protein synthesis in the cell. Ionic, covalent, and peptide bonds are not directly involved in this interaction.
