Question

Quizplus · Accepted Answer

The anticodon on the transfer RNA (tRNA) is complementary in base pairing to the codons on the messenger RNA (mRNA). Therefore, during translation, tRNA with the appropriate amino acid cargo binds to the codon on the mRNA through complementary base pairing between the anticodon on the tRNA and the codon on the mRNA. The ribosome facilitates this process, but it does not directly recognize the codons on the mRNA. Small cytoplasmic RNA does not play a direct role in translating mRNA sequences into amino acid sequences. Aminoacyl tRNA synthetase is responsible for charging each tRNA with the appropriate amino acid, but it does not recognize codons on the mRNA.
