| 摘 要： | 质粒是细小、环状、独立于染色体外，能自主复制的DNA，合有少量基因。原核细胞质粒合有可控制原核细胞发育，转移对药物的耐药性、毒性产物，降解碳源等基因。近代可利用质粒研究各种机体基因结构与功能的关系，作为研究基因工程的工具与技术。

| Abstract: | A plasmid is a small, circular piece of extrachromosomal DNA that is self- replicating and contains a limited number of genes.In procaryotes,plasmid that control such characteristics as fertility, and those that contain genes for transferable drug resistance, toxin production, ability to degrade unusual carbon sources, etc Plasmids are being used to study structure - function relationships of the genes from various organisms, also as tools and techniques for genetic engineering in recent year. |
