63. The characteristic loop on a tRNA molecule that contains modified uridine bases and helps it bind to the ribosome is the

A. D-loop
B. Anticodon loop
C. T-loop (T$psi$C loop)
✓
D. Variable loop

📝 Explanation

The T$psi$C loop contains ribothymidine and pseudouridine, which are critical for anchoring the tRNA molecule to the large ribosomal subunit.
