A diagram shows the three separate components of a nucleotide and how they are combined to form a complete molecule. A nitrogenous base is represented as a purple hexagon. A sugar is represented as a grey pentagon. A phosphate group is represented as a light brown circle. A cut-away from the generic nitrogen base shows the chemical structure of the three types of pyrimidine bases (cytosine, thymine, and uracil) and the two types of purine bases (adenine and guanine).

Building the model helped me understand the structure of DNA because I could "see" what nitrogen bases bonded (Guanine with Cytosine and Thymine with Adenine connected by a hydrogen bond) and understood that a nucleotide consisted of phosphate, deoxyribose sugar, and a nitrogen base.
