Understand that tRNA (transfer RNA) is a type of RNA molecule that helps decode a messenger RNA (mRNA) sequence into a protein during the process of translation.
Recall that mRNA contains codons, which are sequences of three nucleotides that correspond to specific amino acids or stop signals during protein synthesis.
Recognize that tRNA molecules have a specific region called the anticodon, which is a sequence of three nucleotides that is complementary to an mRNA codon.
During translation, the anticodon of a tRNA pairs with its corresponding codon on the mRNA strand, ensuring that the correct amino acid is added to the growing polypeptide chain.
Therefore, the sequence that tRNA contains to pair with mRNA codons is called an anticodon.
