Question

Accuracy in the translation of mRNA into the primary structure of a polypeptide depends on specificity in the ________.a) binding of ribosomes to mRNA.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.

Answer 1

Answer:

d) binding of the anticodon to the codon and the attachment of amino acids to tRNAs.

Explanation:

A transfer RNA (tRNA) is one of the three types of RNA molecules whose job is to match an mRNA codon( a sequence of three DNA or RNA nucleotides that corresponds to a specific amino acid) with the amino acid it codes for.

Each tRNA contains a set of three nucleotides called an anticodon which corresponds to the amino acid encoded by a codon of an mRNA. The amino acid encoded by the codon is also attached to the tRNA molecule. This ensures specificity and accuracy during translation.

Therefore, during the translation of mRNA into the primary structure of a polypeptide, accuracy depends on specificity in the binding of anticodon and attachment of amino acids to tRNA.
