Question

What is false about tRNA?

• A. It binds with an amino acid at 5' end.
• B. It has five base pair stem.
• C. It has anticodon at one end which recognizes the codon on m-RNA.
• D. It looks like clover leaf in the two dimensional structure.

Answer 1

The correct option is A It binds with an amino acid at 5' end.

The t- RNA looks like cloverleaf in a two-dimensional structure. The anticodon arm is a 5-bp stem whose loop contains the anticodon. The amino acid are attached to the cytosine-cytosine-adenine sequence at the 3' end of the tRNA molecule The enzyme aminoacyl-tRNA synthetases to form aminoacyl-tRNA is covalently bonded to the 3'-hydroxyl group on the CCA tail.

So, the correct answer is option A.
