WebThis basic information is stored in the way that the bases match one another on opposite sides of the double helix--adenine with thymine, guanine with cytosine--forming a set of complementary hydrogen bonds. These are shown in the diagram with red arrows. WebNow let’s consider the structure of the two types of nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base (Figure 2). There are four types of nitrogenous bases in DNA.
