原核生物的 meaning in Chinese

procaryotic
prokaryotic

According the traditional concepts , the eukaryotic chromosomes are linear and the prokaryotic chromosomes are circular
传统的生物学观念认为真核生物的染色体是线状的，原核生物的染色体则是环状的。
This has led to the theory ( endosymbiont theory ) that eukaryotes arose as a result of symbiotic associations between prokaryotes
这就形成了真核生物中某些细胞器来自于共生的原核生物的理论（内共生理论）。
Because there are many copies of chloroplast dna and the chloroplast has a strong tolerance to accumulation of the products expressed by the introduced foreign gene , a high level of expression is often happened in chloroplast transformation . in addition , because of prokaryotic property of the chloroplast , the prokaryotic gene can be expressed in chloroplast without any modification and multigene can be simultaneously transferred in " polycistron " , which is impossible in nucleic transformation
另外，由于叶绿体基因组的原核性质，对来自原核生物的外源基因无需改造就可以在叶绿体内高效表达，而且可以将多个外源基因采取“多顺反子”的原核表达形式同时引入，并由共同的启动子控制，既方便操作又可避免由于存在多个相同启动子所带来的“共沉默” 。
