DNA Structure and Shape | Ask A Biologist - Arizona State University A closer look at the chemical structure of DNA shows four main building blocks. We call these nitrogenous bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). DNA also includes sugars and phosphate groups (made of phosphorus and oxygen). These make the phosphate-deoxyribose backbone.

DNA: Structure, Forms and Functions (With Diagram) - Biology Discussion DNA contains β D 2′-deoxyribose sugar. It is a five-carbon sugar; hence it is a pentose sugar. Since one oxygen atom at the 2′ carbon is missing it get its name 2′-deoxy. The 2′- deoxy-containing backbone is more resistant to hydrolysis than the riboform. D-ribose does not mean dextrorotary ribose.
