查询词典 conical helix

In addition, the 3D-model structure of PvFadA is composed of 11 helixes, moreover,α3,α4,α6 and α7 form a core 4-helix bundle to regards as an active center in this enzyme, similar as acyl-ACP desaturase of Ricinus communis and Mycobacterium tuberculosis H37Rv.

PvFadA的3D结构类似于蓖麻和结核分枝杆菌H37Rv的acyl-ACP去饱和酶。

So that it results in the change of the rotatory direction. These changes are accorded with the rule of helix theory.

此断言显然违背了物质的所有性质都是由其结构决定的这一基本化学原理。

Because many kinds of specific helix are contained in every conformation, it is difficult for us to deduce its rotatory direction.

每种构象都包括特有的数种螺旋，很难推断其旋光方向。

On the basis of the helix theory proposed by the authors,the relationship between stereostructure and rotatory direction is analyzed for the fused polycyclic compounds.

通过笔者提出的螺旋理论，分析了多环稠合化合物的立体结构和旋光方向间的关系。

Two men in shirts and ties run back to a white van with DNA double helix ROUSH TECHNOLOGIES logo on the side.

两个穿衬衫打领带的人跑回一辆白色的旅行车，上面有个DNA的双螺旋「劳许科技公司」的标志。

e-PTFE was implanted into the pitting area after subcuntaneous disjunction. Results: 15 cases were followed for about 3 and 6 momths after implant of e-PTFE, including cases with saddle nose, pitting deformity of orbit, congenital lip cleft with depressed soft tissue around pyriform opening, parbial defect of helix. In these cases, satisfaction rate is evaluated as high as 97.9%, unexpected tissue response was not shown in this clinical trail.Conclusion: Depended on this clinical trail, we believe local e-PTFE manufactured by Shanghai Suo-kang Medical Implants Co., Ltd.

由于e-PTFE的组织相容性好，在80年代初期一些发达国家已经应用于整形美容外科[1]，尤其应用于隆鼻术、面部凹陷畸形的整复、唇线增高、唇加厚、鼻唇沟过深的整形美容术、耳廓缺损等手术中，学者们认为e-PTFE排斥反应的发生率低，弹性和硬度与软组织相似，周围组织细胞能够长期进入移植物内，不形成纤维囊，在整形美容外科领域有重要的应用价值。

Replicas of DNA are made when the double helix unwinds as a result of helicase enzyme action and the separated strands serve as templates along which complementary nucleotides are assembled through the action of the enzyme DNA polymerase. The result of the two new molecules of DNA each containing one strand of the original molecule, and the process is termed semiconservative replication.

DNA 的复制在解旋酶解开 DNA 链时开始，解开的链作为模板 DNA 聚合酶的作用下结合相对应的核苷酸，最终形成了两条新的 DNA 的链，每一条的链含有一条链原来的 DNA 单链，因此又叫做半保留复制。

Semiconservative replication :The two strands of DNA double helix are separated, each strand serves as a template for the synthesis of a new complementary strand, producing two daughter molecules. Each daughter molecule has one parental strand and one newly synthesized strand.

半保留复制： DNA 生物合成时，母链 DNA 解开为两股单链，每股单链分别作为模板，以 dNTP(dATP 、 dGTP 、 dCTP 、 dTTP)为原料，按照碱基配对(A － T 、 G － C)规律与模板上的碱基配对，经依赖 DNA 的 DNA 聚合酶催化，合成一条与模板互补的新链，新形成的两个子代 DNA 与亲代 DNA 碱基序列一致，子代 DNA 分子中一股单链是从亲代完整地接受过来，另一股单链是新合成的，故称为半保留复制。

Silicium in our body,triple-helix, size: 1,08 meters ,population 12 billion,other

我们的身体由硅原子组成（注：我们地球人是碳原子组成），DNA为三螺旋结构，身高1.08米，人口12亿

We also got STM images of denatured fibroin under stress or by methanolin molecular level. We found the conformation of silk fibroin is changed from α-helixand random coil structures to β-strand and loosed α-helix formation. We employed the STM to explore the structure and morphology of silk fibroinin the middle silk gland of mature silkworm.

我们在分子水平上对在冰冻和甲醇处理下的丝心蛋白的变性情况进行了STM研究，我们发现丝心蛋白的构象由α-螺旋结构和无规线团的结构向β-伸展链和松散折叠α-螺旋结构转变我们还用STM对熟蚕的中部丝腺体中的丝心蛋白的结构形态进行了研究。
