dna structure造句

• In addition , people who use livestock product and dairy on their diets are at very higher risk for certain health problems . these problems include mutation of dna structure of human body , human immunity deterioration , birth defects and cancer
  人们食用这些药残和重金属含量超标的畜产品和奶产品，日积月累，将导致人体dna结构发生突变，从而使人体免疫力下降，甚至造成“致畸” “致癌”等严重后果。
• Using a semantic grid , you could process dna information using one grid , and identify and manipulate proteins related to that dna structure using another grid , simply by feeding information generated by one grid into the other
  使用语义网格，您可以使用一个网格来处理dna信息，使用另外一个网格对与这个dna结构有关的蛋白质信息进行识别和处理，这可以通过将一个网格生成的数据提供给另外一个网格来实现。
• Both the frequency and intensity of 1146 . 0cm - 1 change largely , etc . discussed and compared the mechanism of these interaction in detail we got some conclusions as following : both zn2 + and cd2 + ions can chelate with po2 - and come into being - po2 - me2 + n7 ( purine ) chelate . as to zn2 + ions , when r2 . 0 , the quantity of po2 - zn2 + n7 is directly linear with r . when r2 . 0 , zn2 + ions even can chelate with c at n3 - o2 sites and this chelation will disrupt the h - bond between gc base pairs and make the dna structure unstable . as to cd2 + ions , only when r is within 1 . 0 - 1 . 5 can this chelation take place and the relation of the quantity of this chelate with r is not easy to conclude
  通过对这些变化进行详细讨论和分析，我们得到了如下的结论： zn ~ ( 2 + )和cd ~ ( 2 + )都可以跟dna的磷酸基团螯合，形成- po _ 2 ~ - … me ~ ( 2 + ) … n7 ( g )螯合物，但是前者的螯合跟离子浓度有很大的关系，在摩尔浓度比小于2 . 0时，螯合物的生成量跟r成正比关系，而后者的螯合跟离子的关系不是很明显，只有当r处于1 . 0至1 . 5之间时，螯合作用才能进行，并且螯合物的生成量跟r之间没有很明显的关系存在。
• Three kinds of data access objects dao , rdo , ado and windows dna structure of three are discussed at length . integration mode of software system is summarized and a set of software is programmed on this basis to realize the database management of experiment data . in addition , another set of vod management system software is programmed to ensure its normal operation and effective management
  本文回顾了数据管理方式的发展历史，对数据库，特别是sqlserver2000进行了比较详细的介绍，讨论了三种数据访问对象： dao 、 rdo 、 ado ，详细讨论了windowsdna三层结构，对软件系统集成方法进行了概述，然后在此基础上编制了一套针对实验数据的数据库管理软件，实现了对实验数据的数据库管理，另外还在导师原有科研工作的基础上，进行理论分析，并改进编制了一套视频点播管理系统软件，实际运行证明，可保证视频点播系统的正常运转和有效管理。
