Any of various microorganisms of the domains Archaea and Bacteria, characterized by the absence of a distinct membrane-bound nucleus and membrane-bound organelles and by the simultaneous occurrence of DNA transcription and protein synthesis at the same site, in contrast to eukaryotes. Also called moneran.

[French procaryote : Greek pro-, before; see pro-2 + Greek karuōtos, having nuts (from karuon, nut; see karyo-).]
