Where would you find the anti-codon?

The anti-codon is specifically found on the tRNA (transfer RNA) strand. Each tRNA molecule has a unique three-nucleotide sequence called the anti-codon, which is complementary to a corresponding codon on the mRNA (messenger RNA) strand during protein synthesis. This pairing enables the tRNA to bring the correct amino acid to the ribosome, ensuring that proteins are synthesized accurately according to the genetic code.

When the tRNA's anti-codon pairs with the mRNA's codon, it facilitates the addition of the appropriate amino acid to the growing polypeptide chain. This process is crucial in translating the genetic information encoded in the DNA into functional proteins. The presence of the anti-codon on the tRNA is essential for maintaining the fidelity of protein synthesis because it dictates which amino acid is incorporated based on the mRNA sequence.
