1894, from German cytosin (1894), from cyto- "cell" + -ose + chemical suffix -ine (2). "The name cytosine (due to Kossel and Neumann) is misleading. Cytosine is not, like adenosine and guanosine, a nucleoside but the sugar-free base." [Flood]

In a little under sixteen weeks they tried corticosteroids, L-aspiraginase, cytosine arabinoside, massive irradiation, and mercrystate crystals, with no more success than they'd expected, which was none and negatory.
Each side of these base pairs can either be an adenine -thymine or a guanine -cytosine bond, and they can be aligned either direction, so there are four choices.
In fact, adenine, guanine, thymine, and cytosine molecules have quite different structures, and their electron density distributions as seen by a scanning probe microscope are readily distinguished by an experienced eye.
