我们仍然需要解释的是更特化的真核生物的磷酸化途径是怎么进化而来并取代了细菌的系统。
What still needs to be explained is how the more typical eukaryotic phosphorylation cascades evolved and came to replace the bacterial systems.
“这给了真核生物基因原料,使它们能够积累新的基因。从规模上来讲,重大基因家族和调节系统对于细菌来讲是完全无法负担的”莱恩博士说。
"This gives eukaryotes the genetic raw material that enables them to accumulate new genes, big gene families and regulatory systems on a scale that is totally unaffordable to bacteria," said Dr Lane.
但需要特别注意的是:他只是统计了真核生物,也就是那些细胞相对复杂的动物,而把细菌以及古生菌排除在外了。
But there are some important caveats: it counts only the eukaryotes, that is, critters with relatively complex cells.

All of life can be divided into three domains: Eukarya (including plants, animals, fungi, and other organisms) Bacteria, and Archaea.
这种基因调控模式不仅限于真核生物,细菌利用小分子rna,尤其是那些从CRISPR位点沉默的噬菌体,转座子和质粒表达。
This mode of gene regulation is not restricted to eukaryotes; bacteria utilize small RNAs, notably those made from CRISPR loci that silence the expression of bacteriophages, transposons and plasmids.
当类似古细菌的细菌存在于形态组织及基因组中时,其基因组复制方法表现出类似真核样。
