a group of three mRNA nucleotides is called a codon, which meets complementary triplet of tRNA nucleotides, called an anticodon, in the ribosomes. Carboxyl(also called acid), amino, and the radical which is what is changed to make an amino acid unique.
As the new nucleotides line up opposite each parent strand by hydrogen bonding, enzymes called DNA polymerases join the nucleotides by way of phosphodiester bonds. Actually, the nucleotides lining up by complementary base pairing are deoxynucleoside triphosphates, composed of a nitrogenous base, deoxyribose, and three phosphates. As the phosphodiester bond forms between the 5' phosphate group of the new nucleotide and the 3' OH of the last nucleotide in the DNA strand, two of the phosphates are removed providing energy for bonding.
