  • IPA(key): /ˈæ.dəˌniːn/, /ˈæ.dɪˌnɪn/

Noun[edit]

adenine (countable and uncountable, plural adenines)

  1. (biochemistry, genetics) A base, C5H5N5, found in certain glands and tissues, which pairs with thymine in DNA and uracil in RNA.

      One of these labels is ethenoadenine, which is obtained by chemical modification of adenine.
    • 2006, David Markie, “1: Markers, Selection, and Media in Yeast Artificial Chromosome Cloning”, in Alasdair MacKenzie, editor, YAC Protocols[2], 2nd edition, page 2:
      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.
