sd序列 meaning in Chinese

sd sequence
shine-dalgarno sequence

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 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。
