Approximately half of all eukaryotic genes show signs of prokaryotic origin. Genes derived from eubacteria are more abundant than those from archaebacteria, but the latter are functionally more important. This supports archaebacteria as founding ancestors of the eukaryotic nucleus.
大约一半的真核基因显示出原核起源的迹象。源自真细菌的基因比源自古细菌的基因更丰富,但后者在功能上更为重要。这支持了古细菌是真核细胞核的原始祖先。
