B) binding of the anticodon to small subunit of the ribosome
C) attachment of amino acids to rRNAs
D) binding of the anticodon to the codon and the attachment of amino acids to tRNAs

Question

Quizplus · Accepted Answer

Accuracy in translation depends on the specific binding of the anticodon of a tRNA to the codon on the mRNA, as well as the attachment of the corresponding amino acid to the tRNA. This ensures that the correct amino acid is added to the growing polypeptide chain in the correct order. The binding of ribosomes to mRNA and the binding of the anticodon to the small subunit of the ribosome are important steps in translation, but they do not directly contribute to the specificity of the process. The attachment of amino acids to rRNAs is not a process that occurs in translation.
