     One of these labels is ethenoadenine, which is obtained by chemical modification of adenine.

     There are two genes in the adenine biosynthetic pathway of yeast (ADE1 and ADE2) that, apart from producing an absolute requirement for adenine when mutant, also produce a change in colony color.

     The HCN pentamer, adenine (a constituent of DNA, RNA and many coenzymes), is one of the most abundant biochemical molecules.
