Modified Nucleosides
A defining characteristic of functional $\text{tRNA}$ is the extensive presence of chemically modified nucleosides beyond the canonical four bases ($\text{A, U, G, C}$). Over 50 distinct modifications have been cataloged across various organisms. These modifications are crucial for stabilizing structure, ensuring accurate codon recognition, and regulating translational kinetics.
Notable modifications include:
