sd sequence meaning in English
sequence]夏因-达尔加诺序列
夏因-达尔加诺序列,s-d序列
Examples
- Analysis of sd sequence of cry id showed that it was obviously different from that of other cry genes published
分析cry1d基因的sd序列，发现与已报道的其它cry基因的sd序列不同。 - The promoter - probe vector phn117 in e . coli and phn127 in g " were further constructed by removing promoter while keeping sd sequence from phn115 . a teta / tetr bidirectional promoter fragment from pbr322 was respectively cloned into phn117 and phn127 and the resulted colonies were all fluorescent
并经插入pbr322上665bpteta tetr双向启动子片段后得到的转化子均发绿色荧光验证，实现了wtgfp在大肠杆菌和华癸中生根瘤菌中的组成型表达。 - The pa7 fragment was sequenced and several motifs similar to prokaryotic promoter elements such as - lobox , - 35box and up box were found . the sd sequence which was bound by ribosome and atg site were also found . the pat fragment was blast in genebank , but there is no its " homological sequence
对pa7片段的序列分析发现其距5 ’端931bp ? 1091bp处具有原核生物典型基因启动子的保守结构- 10区和- 35区，以及翻译必需的sd序列和翻译起始位点等。 - After site - mutation using pcr was introduced into cryld sd sequence ( gggga - ggagg ) , cryld - lacz expressed higher 1 . 0 - 1 . 6 times than before mutation , suggesting that ggagg might be most effective sd sequence for bacillus thuringiensis , meanwhile , low translational initiation efficiency caused by improper sd sequence might lead to low expression of cryld in hd133
利用pcr定点诱变技术突变其sd序列gggga为ggagg后， cry1d - lacz融合基因的表达提高了1 . 0 - 1 . 6倍。表明ggagg同样是苏云金芽胞杆菌最有效的sd序列，同时也揭示了基因cry1d表达量低的原因之一是不合适的sd序列而导致较低的翻译起始效率。
