What ensures that the correct amino acid is added during translation?
A) the anticodon of a properly formed aminoacyl tRNA
B) the methyl-guanosine cap of a properly modified mRNA
C) the poly-A tail of a properly modified mRNA
D) the twisting number of a properly supercoiled DNA

Question

Quizplus · Accepted Answer

During translation, the correct amino acid is added to the growing polypeptide chain by the complementary base pairing between the codon on the mRNA and the anticodon of a properly formed aminoacyl tRNA. Each tRNA is specific for one amino acid, and the anticodon recognizes only the codon for that amino acid. Therefore, the anticodon of a properly formed aminoacyl tRNA ensures that the correct amino acid is added during translation. The other options (B, C, and D) are not involved in the process of adding the correct amino acid during translation.
