Correct Answer: B
Solution :
[b] tRNA or transfer RNA is a single stranded molecule and takes the shape of a clover leaf. In the process of transcription tRNA brings amino acid and reads the genetic code and acts as an adapter molecule. In the given structure of tRNA, the labels A, B, C and D are respectively AA binding site (amino acid binding site), T \[\psi \]C loop, anticodon loop (codon recognition site) and DHU loop (amino acid recognition site).
