उत्तर
It extends from one end of a tRNA molecule.
Explanation:
A codon is a specific sequence of three nucleotides found on a messenger RNA (mRNA) molecule, not on a transfer RNA (tRNA) molecule. The corresponding triplet found on the tRNA is actually called an anticodon, which pairs with the mRNA codon during protein synthesis.
