What is the role of the DHU arm of a tRNA molecule?
Options:
Answer:
A
Solution:
The tRNA molecule has several specific regions with distinct functions:
The DHU loop (dihydrouridine loop) acts as the recognition site for the specific aminoacyl-tRNA synthetase enzyme, which is responsible for adding the correct amino acid. Hence, it is known as the amino acid recognition site.
The 3' end (CCA sequence) is the amino acid binding site where the amino acid physically attaches.
The anticodon loop is the codon recognition site that pairs with the mRNA codon.
The TC loop is the ribosome recognition site.
Answer: Amino acid recognition site.
