Question

Accuracy in the translation of mRNA into the primary structure of a polypeptide depends onspecificity in theA) binding of ribosomes to mRNA.B) shape of the A and P sites of ribosomes.C) bonding of the anticodon to the codon.D) attachment of amino acids to tRNAs.E) bonding of the anticodon to the codon and the attachment of amino acids to tRNAs.

Answer 1

Answer:

The correct option is E.

Explanation:

Protein synthesis in living cells is divided into two distinct stages, which are transcription and translation. Transcription occurs in the nucleus where mRNA is formed from DNA. The mRNA then moved into the cytoplasm, where the process of translation takes place. Translation occurs in 5 stages and the accuracy of this process depend on the bonding of the anti-codon to the codon and the attachment of amino acids to tRNA.

tRNA (transfer RNA) plays a vital role in the translation process. It has very specific structures, which have the ability to bind to specific amino acids at one end and an mRNA molecule at the other end. This arrangement ensures that accuracy is maintained by making sure that each amino acid is carried to the appropriate point in the protein that is been synthesized based on the information in the mRNA.
