Macromolecule 4: Nucleic Acids
Deoxyribonucleic acid (DNA) is the nucleic acid found in the nucleus of all eukaryotic cells. It contains the code of life. In this nucleic acid, two anti-parallel strands of amino acids are connected to one another by hydrogen bonds. Adenine bonds to thymine with two hydrogen bonds while guanine and cytosine are connected by three hydrogen bonds. The structure is similar to that of a twisted ladder.
