This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Molecular Genetics, Subject name: Biochemistry
Anticodon is present in - 
Select and explain. 
A. mRNA, B. tRNA, C. rRNA, D. hnRNA
B: tRNA
Answer: B: tRNA 
Explanation: Ans. is 'b' i.e., tRNA o t-RNA molecule get folded into a structure that appears like a clover leaf Q. There are four arms.Acceptor arm : It consists of a base paired stem that terminates in the sequence CCA at the 31 end. This is the attachment site for amino acids.D arm - It contains the base dihydrouridine (D).Anticodon arm - It contains anticodon Q that base pairs with the codon of coming mRNA. Anticodon has nucleotide sequence complementary to the codon of mRNA and is responsible for the specificity' of the t RNA.T C arm : It contains both ribothymidine (T) and pseudouridine (ps).
