The Nitrogenous Bases; The nitrogenous bases connect to the backbone by bonding to the sugars. ... Because of the nature and shape of these connections, DNA spirals into a double helix, a shape that can be best described as a twisted ladder (the nitrogenous bases would be the rungs).

(2) Nitrogenous bases. There are two types of nitrogenous bases, pyrimidines and purines. The pyri­midines are single ring compounds, ... The weak hydrogen bonding enables the two strands of the DNA to separate during replication. The pyrimidine and purine bases are linked to the deoxyribose sugar molecules.
