Question

Identify the labelled parts from the following image.

• A. A-amino acid binding site, B-DHU loop, C-TѱC loop, D-anticodon loop
• B. A-anticodon loop, B-amino acid binding site, C-extra arm, D-TѱC loop
• C. -TѱC loop, B-anticodon loop, C-extra arm, D-amino acid binding site
• D. A-DHU loop, B-TѱC loop, C-anticodon loop, D-amino acid binding site

Answer 1

The correct option is A A-amino acid binding site, B-DHU loop, C-TѱC loop, D-anticodon loop

A molecule of tRNA has five single-stranded regions - amino acid (AA) binding site, TѱC loop, DHU loop, the extra arm and the anticodon loop. Each of them plays a unique role in protein synthesis.
