What nucleic acid does the anticodon bond to?
The anticodon nucleotide bases base pair with the codon bases.
The codon sequence is on the mRNA. It is 3 nucleotides in length. As the mRNA is thread through the ribosome, a tRNA with an anticodon loop that matches the codon on the mRNA enters the A-site of the ribsome. It is in this way that mRNA code for a specific amino acid. The codon base pairs with the anticodon of the tRNA - to which is attached the amino acid.
