When this term is used for annotation, it indicates that no information was available about the biological process of the gene product annotated as of the date the annotation was made; the evidence code 'no data' (ND), is used to indicate this. A process that emerges from two or more causally-connected macromolecular activities and has evolved to achieve a biological objective.
