查询词典 helix

Lucidum. Then we clone the gene, glfks1 and glfks2. Hydropathy analysis predicts that GlFks1 and GlFks2 are integral membrane protein with about 16 and 14 transmembrane helices.In genomic southern blot analysis, glfks1 and glfks2 both are single copy gene.

cerevisiae相关之β-(1，3)-D-葡聚醣合成酶基因fks相似之序列，并将其选殖出来，分别得到glfks1与glfks2，利用hydropathy分析，显示GlFks1与GlFks2分别具有16个与14个transmembrane helix，且推测GlFks1与GlFks2应也是属於嵌入的membrane protein。

在一般的短链分子溶剂中，只有在温度降至很低，等规聚苯乙烯的分子链才有可能部分规整排列。

Since Watson and Crick have brought forward the model of DNA helix structure and explain about it's reproduce mechanism in molecule level, research work concerning DNA has been continuously lucubrated. However, whether translating inheritance information and rebuilding DNA molecule via menstruating DNA sequence, or to date the most compelling gene project, chromosome protract et. al, there all need a sort of molecule scissors cleaving DNA, DNA cleavage reagent. At present, tool enzyme of cleaving DNA is mostly DNA restriction enzymes founded in 70 years, which only cleave DNA at specific 4-8 base pair sequences that are usually palindromic, so this restricts the at very fast speed developing of gene technology at certain extent.

自从Watson和Crick提出DNA的双螺旋结构并对其复制机制在分子水平上进行解释后，使得对DNA的研究不断深入，但无论是通过测定DNA的序列来破译遗传信息、改造DNA分子，还是目前最令人关注的基因工程、染色体绘制等，都需要一种断裂DNA分子的&剪刀&——DNA断裂试剂，目前断裂DNA的工具酶主要是上个世纪70年代发现的DNA限制性内切酶，但所知的Ⅱ型限制性内切酶的DNA序列识别长度较短（约为4～8个碱基对），而且一般要求回文结构，这就给飞速发展的基因工程技术带来一定的限制。
