小亚基（SSU）和大亚基（LSU）的核糖体RNA基因的序列从古细菌，真细菌，核，叶绿体和线粒体的真核生物进行了比较，以确定最保守的位置。已使用SSU和LSU rRNA的这些位置的对齐集合来生成与源生物体/细胞器相关的树形图。使用统计自举技术评估分支模式。由此产生的SSU和LSU树是非常一致的，并显示出高度的相似性与那些基于替代数据集和/或由不同的技术产生的。除了提供深入了解原核和真核（核）谱系的进化，这里报道的分析提供了，第一次，广泛的线粒体谱系的同源性。
Sequences of small subunit (SSU) and large subunit (LSU) ribosomal RNA genes from archaebacteria, eubacteria, and the nucleus, chloroplasts, and mitochondria of eukaryotes have been compared in order to identify the most conservative positions. Aligned sets of these positions for both SSU and LSU rRNA have been used to generate tree diagrams relating the source organisms/organelles. Branching patterns were evaluated using the statistical bootstrapping technique. The resulting SSU and LSU trees are remarkably congruent and show a high degree of similarity with those based on alternative data sets and/or generated by different techniques. In addition to providing insights into the evolution of prokaryotic and eukaryotic (nuclear) lineages, the analysis reported here provides, for the first time, an extensive phylogeny of the mitochondrial lineage.
