Answer to Question #190615 in Molecular Biology for Junave

Question

How can many different DNA molecules be made up of only four bases?

Answer 1

A nitrogenous base is an organic molecule that contains nitrogen and has the chemical properties of a base. There are four nitrogenous bases that occur in DNA molecules: cytosine, guanine, adenine, and thymine (abbreviated as C, G, A, and T). These bases represent an intermediate state in the demethylation process, they could be important for cell fate reprogramming and cancer, both of which involve DNA demethylation.
