The anticodon that would interact with the given codon, CCU has to be predicted. Concept introduction: A three nucleotide sequence in mRNA molecule that codes for a specific amino acid is known as codon. The complementary three-nucleotide sequence of a codon is known as an anticodon. The codon is present on a mRNA molecule while an anticodon is present on a tRNA molecule.
