#Question id: 764

Which of the following is NOT correct about tRNA?

#Unit 1. Molecules and their Interaction Relevant to Biology

  1. Charging tRNAs with amino acids is mediated by aminoacyl-tRNA synthetases.

  2. tRNA contains a three-nucleotide sequence known as an anticodon.

  3. Some tRNAs can bind to more than one codon due to wobble base pairing in the second base of the codon.

  4. The match between tRNA anticodon and the mRNA codon ensures the fidelity of translation.
