Abstract

The divergence of nucleated organisms and bacteria was 2.6 times more remote in evolution than the divergences of the nucleated organisms into sparate kingdoms, as evidenced by genetic changes in cytochrome c and transfer RNA. The development of the genetic code through the differentiation of transfer RNA's for different amino acids was still more remote in evolution. The overall states of transfer RNA evolution in bacteria and nucleated organisms were comparable.

摘要

有核生物与细菌在进化上的分化程度，比有核生物分化为不同界的分化程度要远2.6倍，这一点由细胞色素c和转运RNA中的基因变化所证明。通过针对不同氨基酸的转运RNA的分化而形成遗传密码，在进化上更为久远。细菌和有核生物中转运RNA的总体进化状态是可比的。
