उत्तर
Modified bases are especially abundant in tRNA molecules compared to other RNA types. These modifications, including pseudouridine (Ψ), dihydrouridine (D), and inosine (I), are essential for proper tRNA folding, stability, and recognition by aminoacyl-tRNA synthetases and the ribosome during translation.
