  1. A group of related and closely linked structural genes, together with the operator gene that controls their expression are collectively called an operon.

    一組相關的、緊密連鎖的結構基因加上控制其表現的操縱基因，統稱操縱子。
  2. Then the engineered genes of bio operon were carried on testing of the functional expression, and biow & biob gene were induced to express

    而後對改造后的生物素操縱子基因進行了功能表達檢測及biow與biob基因的誘導表達。
  3. Operon is a unit of bacterial gene expression and regulation, including structural genes and cis - acting control elements in dna recognized by regulator gene product ( s )

    控制某一代謝途徑的相關基因，緊密連鎖地排列在一起，受同一操縱子控制。
  4. However, in the late phase of the growth, the strain hv grew a little faster than e. colihms174. hv ( ptz101 ) was constructed by the plasmid containing the phb operon and the parde gene tansformed into the strain hv

    將帶有phb操縱子和質粒穩定分配基因parde的質粒ptz101引入vhb整合菌中，構建成為產phb的vhb整合菌hv （ ptz101 ） 。
  5. The c - phycocyanin ( cpc ) operon of blue - green alga ( or cyanobacteria ) arthrospira platensis fachb341 was cloned, sequenced and characterized by using chromoseme walking method. the sequence includes cpcb gene ( 519 bp ), cpca gene ( 489 bp ), cpch gene ( 357 bp ), and upstream sequence of cpcb ( 427 bp ) and upstream sequence of cpch genes ( 184 bp ), 111 bp of phycocyanin intergenetic spacer ( pc - igs ). upstream sequence of cpcb gene was ligated into promoter - probe vector pegfp - 1 and transformed into three systems : e. coli, synechocystis pcc 6803 and a. platensis fachb341 by supersonic and electrophoresis methods

    根據genbank中報道的節旋藻藻藍蛋白基因序列設計引物，首先克隆了鈍頂節旋藻（ arthrospiraplatensisfachb341 ）藻藍蛋白操縱子中亞基基因、亞基基因部分序列及二者之間的間隔區序列（ pc - igs ）並進行序列測定，然後根據此測序結果設計引物，通過染色體步移法克隆得到藻藍蛋白操縱子長度為2086bp的基因片段，其中包括藻藍蛋白亞基基因（ cpcb ， 519bp ） ，亞基基因（ cpca ， 489bp ） ，連接蛋白h基因（ cpch ， 357bp ） ，亞基基因上游啟動子序列（ 427bp ）以及各基因之間的間隔區（ pc - igs ， 111bp ； cpch與cpca間隔區， 184bp ） 。
  6. Using pcr technology, a 2. 4kb dna fragment, part of tryptopanase operon, containing a promoter, a regulator gene tnac located downstream of the promoter and a desired tryptopanase gene tnaa which can be expressed by the promoter from e. coli k - 12, was cloned to pmd18 - t vector. the dna sequence is the same as which was published on science

    為了證明質粒上的基因能表達出有活性的色氨酸酶，將這個dna片段克隆到pet28c質粒的bamhi和hind位點上，使該片段受t7rna聚合酶的啟動子控制，然後轉化噬菌體de3的溶源菌bl21 （ de3 ） 。
