'''Uraziloa''' [[RNA]]n dagoen [[base nitrogenatu]]etako bat da (besteak [[adenina]], [[guanina]] eta [[zitosina]] izanik; [[timina]] ere base nitrogenatua da, baina ez dago [[RNA]]n, [[DNA]]n baizik). Base nitrogenatu pirimidinikoa da, pirimidinatik eratortzen baita. [[Transkripzio]]an eta hainbat [[birus]]en kate bikoitzeko RNAn uraziloa beti adeninarekin elkartzen da, [[hidrogeno zubi]]en bitartez.
Uraziloaren nukleosidoa uridina da; fosforilatzen denean [[nukleotido]] batzuk agertzen dira: uridin monofosfatoa, uridin difosfatoa eta uridin trifosfato izenekoak.
