多顺反子 meaning in Chinese
multicistronic mrna
polycistron
Examples
- Like eukaryotes , but unlike bacteria , they have introns in their transfer rna , but like bacteria they have polycistronic operons ( gene regulators )
像真核生物而不像细菌，转运rna中含有内含子，还有细菌不具备的多顺反子的操纵子（基因的调控子） 。 - 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” 。
