low copy number meaning in Chinese

拷贝数

Hdgs induction by progeny containing a low copy number of the vector was also dramatically higher than induction by single copy vectors . the reduction of gfp protein and mrna abundance , and the presence of 21 - 26 nt sirnas could be simultaneously detected in silenced plants and the gfp coding region of these plants was methylated extensively
在发生沉默的植株体内，在gfp蛋白及其rna被不同程度降解的同时，可以检测到21 - 26nt的小分子rna ( sirna ) ，同时gfp基因编码区也受到显著地甲基化修饰。
Streptomyces low copy number plasmid scp2 * is also employed for the cloning and recovery of large dna fragment from streptomyces . as scp2 * can accommodate large dna insertions and is efficiently transmissible among its permissive hosts such as s . lividansbut seemed to be unable to replicates in streptomyces sp . fr - 008 , it might be a suitable vector for the cloning of the entire fr - 008 pks gene cluster through gene replacement followed by conjugation with 5
Scp2 *可以在变铅青链霉菌等许可宿主内复制并在许可宿主间有效转移，但似乎不能够在链霉菌fr - 008中复制，因此可能适合于在链霉菌fr - 008中通过进行基因置换及随后的链霉菌fr - 008和变铅青链霉菌间的接合过程来克隆完整的fr - 008生物合成基因簇。
