Question

a.Binding of ribosomes to mRNA

b.Shape of the A & P sites of ribosomes

c.Bonding of the anticodon to the codon

d.Attachment of amino acids to tRNAs

e.Both the bonding of the anticodon to codon and attachment of amino acids to tRNAs

Answer 1

Accuracy in protein synthesis depends on both the precise pairing between the anticodon of a tRNA and the codon of an mRNA, and the correct attachment of amino acids to their corresponding tRNAs.

Step-by-step explanation:

Accuracy in the translation of mRNA into the primary structure of a protein is crucial for ensuring that proteins are synthesized correctly. This accuracy is reliant on two key interactions:

• The bonding of the anticodon to the codon ensures that the correct tRNA, with its specific amino acid, is brought to the corresponding mRNA codon.
• The precise attachment of amino acids to tRNAs is ensured by aminoacyl-tRNA synthetases, which match the correct amino acid to its appropriate tRNA.

Therefore, the specificity in the binding of ribosomes to mRNA, the shape of the sites within the ribosome, and the role of rRNA are essential but do not directly answer the question at hand, which targets the precision during translation. The correct answer to the student's question is e. Both the bonding of the anticodon to codon and attachment of amino acids to tRNAs.
