Here's why:

* tRNA's role: tRNA molecules are responsible for bringing the correct amino acid to the ribosome during protein synthesis.

* Anticodon: The anticodon is a three-nucleotide sequence on the tRNA molecule that is complementary to a specific codon on the messenger RNA (mRNA). This pairing ensures the correct amino acid is added to the growing polypeptide chain.

So, tRNA is the molecule that contains the anticodon, which plays a crucial role in translating the genetic code into proteins.
