Question

Amino acid acceptor arm of tRNA lies at

• A. 3’ end
• B. 5’ end
• C. DHU loop
• D. TΨC arm

Answer 1

The correct option is A 3’ end

The tRNA molecule has a clover-leaf-like secondary structure. It contains the DHU loop or the D loop, the TΨC arm or the T loop, the anticodon loop and the amino acid acceptor end.

The amino acid acceptor arm is located at the 3' end of the tRNA molecule. A specific tRNA binds to a specific amino acid through its acceptor stem.
