What is the name given to the three-nucleotide bases on tRNA that are complementary to an mRNA codon?

• A. Anticodon
• B. Codon
• C. Exon
• D. Intron

Answer: (A)

The anticodon is the three-nucleotide sequence on tRNA that recognizes the mRNA codon during translation. It pairs with the codon in an antiparallel, complementary fashion, ensuring the correct amino acid is incorporated into the growing polypeptide. The codon itself resides on the mRNA, while exons and introns are parts of gene structure and are not involved in tRNA–mRNA base pairing. Sometimes there is wobble at the third position, allowing a single tRNA to recognize more than one codon, but the essential idea is that the anticodon on tRNA recognizes the codon on mRNA to translate the genetic code accurately.
