the secondary structure of tRNA (transfer RNA) is often depicted as a clover-leaf . However, in its actual three-dimensional (3D) structure, tRNA is a compact molecule that looks like an inverted L . This structural configuration allows it to function effectively as an adapter molecule, carrying a specific amino acid at its 3' end while interacting with the mRNA code via its anticodon loop . Understanding these molecular structures is vital for exam success, as NCERT textbooks serve as the definitive primary source for approximately 95% of NEET Biology questions .
