DNA Composition • DNA is often viewed in its double helix formation, which resembles that of a twisted ladder. • The ‘rungs’ of the ladder are composed of nitrogenous bases, of which there are four types: adenine (A), guanine (G), thymine (T), and cytosine (C). • Adenine and guanine are purines • thymine and cytosine are pyrimidines. • Each nitrogenous base has a unique structure • Each base is chemically linked to the sugar deoxyribose. • A base plus deoxyribose is cal...
