Cervical cancer induced by HPV18 is a result of co-effecting by polygene and multiple factors.

HPV18引发宫颈癌是多因素多基因共同作用的结果，它们通过相互调节、网络调控直接或间接地导致宫颈癌的发生发展，可望进一步分析证实以明确HPV引发宫颈癌的精确分子机制。

The genetic relationships of 11 cultivars and lines in Pennisetum were analyzed using random amplified polymorphic DNA markers. A total of 82 reproducible RAPD fragments were produced using 8 random primers.

利用RAPD分子标记技术分析狼尾草属11个品种12份材料间的遗传关系，结果发现7个引物共扩增出82条带，其中多态性条带为60条，多态位点达73.2%，表明在这11个品种间具有较高的遗传多样性。

Amplified fragment length polymorphism was used to analyze the genetic diversity of 92 Torreya grandis from 6 different populations. Total of 364 loci of the T.grandis genome were examined for molecular variation and 63 loci were polymorphic.

利用AFLP分子标记技术，采用8对引物对6个香榧天然群体的92个个体进行了总基因组DNA水平上的多态性检测，共检测出364个位点，其中多态性位点63个。

Even before you start chewing, stir your food around. This has the effect of aerating the molecules in the food, releasing more of their scent.

在开始咀嚼前，先将食物搅拌一下，这将使食物接触更多的氧气分子，散发出更多的味道。

It was confirmed that facultative apomixes is existed in coffee species based on emasculating treatment, cyto-genetic observe and SSR marker detection.

细胞遗传学观察发现咖啡四倍体类型材料(2n=4x=44)的多胚和多胚苗中含有天然的单倍体胚和单倍体小苗(2n=2X=22)；去雄处理后，可见子房膨大，其中5份材料获得了果实和种子，初步说明无融合生殖现象的存在；对小粒种品种间杂交F1代个体的SSR分析，发现多胚苗中存在与母本图谱相同且不携带父本特异带的后代以及携带双亲特异带的有性后代，表明子代有仅来自母本的无融合生殖个体分离出来。 3 建立了咖啡无融合生殖的分子鉴别方法。

Genetic variation in demes appeared 8 times higher than among demes. The paper also gave a few methods such as dendrogram, statistic, frequency of markers, polymorphic bands and special loci, genetic variations within and among demes for conservation and utility, molecular checking indexes for cultivars can provide basic information for protection of intellectual property rights and selection of wanted cultivars.

通过多态带和特殊带提出了桃核心种质，并利用聚类法、统计法、标记频率法、多态带数和特殊位点法、类群间和类群内的遗传差异法提出了种质保存策略；以及品种识别分子检索表的建立，为知识产权保护和正确选择品种提供了第一手资料。

Methods: Using GV1 and GV2 targetable non-viral vectors, the influences of the poly-L-lysine and protamine on in vitro gene transfer efficiency and the course of gene expression were observed. Results:β-galactosidase was expressed at intermediate level (50%) in A375 cells using a complex containing either protamine or poly-L-lysine.

目前，大部分受体介导的靶向性非病毒载体都利用多聚赖氨酸作为骨架分子来包裹DNA形成复合体，并在实验室研究中取得了较好结果，但由于多聚赖氨酸的临床安全性未知，难以应用于临床研究。

There were two genotypesin China Merino fecundity sheep,the BB and B+ mutation genotype was superior in Chinese merino fecundity sheep,the ewes with genotype BB and B+had 4.0 and 3.5 ovulations,genotype ++ had 1.56 ovulations averagely,The BB and B+ mutation genotypes were 2.44(P.01)and 1.94(P.01)ovulations more than with genotype ++ in the Chinese merino sheep.

绵羊的多胎是绵羊业多产、高产的基础。一般来说，家畜的繁殖性状是受多基因控制的数量性状，传统的选择方法对其遗传进展的改良是很慢的，世代间隔长。分子标记辅助选择为解决这一问题提供了新的方向和契机。

An armed gang freed more than 50 prisoners from a jail in Zacatecas in Mexico, including some two dozen members of the Zetas, a powerful drug-trafficking syndicate.

一群武装分子从墨西哥萨卡特卡斯的一所监狱里解救了50多名囚犯，其中包括20多名Zetas集团成员，Zetas是一个非常有势力的贩毒集团。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
