WebJun 8, 2024 · Multiple nucleotides in the pre-tRNA are chemically modified, altering their nitorgen bases. On average about 12 nucleotides are modified per tRNA. The most … WebFor example, if the amino acid that attach to the end is alanine, the reaction will be catalyzed by alanine-tRNA synthase to produce tRNA phe. The other end—the bottom often called the "DNA arm"—consists of a three base sequence that pairs with a complementary base sequence in a mRNA. See also. Plaque hybridization; References
