查询词典 recombination

Previous research indicated a drastic ontogenetic change in behavior, habitat, body shape, and recombination of tissue during metamorphosing from leptocephalus to juvenile stages. A maximum otolith increment width and sharp decreasing in otolith Sr/Ca ratios resulting from glycosaminoglycan broken–down were observed during metamorphosis.

研究指出，柳叶鱼仔鱼转换到稚鱼的变态过程，须经历行为、栖地转换与身体组织重组等个体发生的剧烈变化；在此过程将观察到耳石日周轮明显变宽、耳石Sr/Ca比因GAGs降解而急速下降等现象。

Similar to the border trap capacitance at low-frequency C-V curves, additional recombined charge per cycle at low-frequency charge pumping measurements could be attributed to the repetitive recombination of majority and minority carriers which instantly tunnel into and out of the border traps located near the high-k/oxide interface.

如同在低频电容—电压图形中的边界缺陷电容值一般，在低频电荷泵浦方法中所量测到的额外每单位循环再结合电荷载子数目，皆可归因於反覆的多数与少数载子再结合，而此一现象主要发生於高介电常数介电层/二氧化矽氧化层介面附近的边界缺陷。

Genetic recombination is the most important event of meiosis and provides genetic diversity for organisms to adapt the environment change.

基因重组是减数分裂中最重要的事件，它为子代提供了新的遗传信息，是生物多样性的基础之一。

Coli XL-1 strain, purposed cassette recombination plasmids pNB0098-K and pNB0097-K were constructed, in which the purposed gene was linked with plasmid pUC18, and the marker gene kanamycin was inserted in the purposed gene. The linear cassette DNA fragment was mixed in the medium of cultured competent cells of meningococcus BT878. The function of the purposed gene was inhibited by the homologous replace of casstte gene.

将线性的重组质粒片段置于培养基中，与感受态的脑膜炎双球菌混合培养，重组质粒中的同源性片段被脑膜炎双球菌细胞识别和摄取，整合到染色体上，目的基因被带有卡那霉素基因插入的同源性重组片段代替，导致失活，在选择性培养基上筛选出基因被敲除的突变株。

The FLP/frt sitespecific recombination system fitting for monocotyledonous crops was constructed to breed the markerfree transgenic monocotyledons with high tolerance to salt and drought.

为培育去除选择标记基因的抗盐耐旱单子叶转基因植物，构建了适合于单子叶植物的FLP/frt位点特异性重组系统。

This kind of new virus is caused by recombination between ACMV and EACMV, and there could be a lot of types of recombinant hybrid virus; The cassava mosaic disease before the epidemic was caused by isolates of ACMV.

杂种病毒可能也存在多种类型，这是二个已知的植物病毒基因组重组产生新病毒的首次报道。同时表明乌干达严重木薯花叶病非流行区的木薯花叶病为ACMV引起。

The excitonic properties about recombination,transfer andscattering in semiconductors and superlattices are an importantresearch topic because of the optical properties of superlatticesand multiple quantum well in band edge depended on the excitonicfeature.

在半导体超晶格中，激子的行为决定了超晶格和量子阱的很多光学性质。因此有关激子的复合、跃迁及散射过程是一项重要的研究课题。

The scope for horizontal gene transfer is essentially the entire biosphere, with bacteria and viruses serving both as intermediaries for gene trafficking and as reservoirs for gene multiplication and recombination (the process of making new combinations of genetic material).

方舟子的这一观点来自侯女士的另一个证据就是，他在作于2005年1月的《答〈中国青年报〉记者刘县书的批评》中写道：HGT"是近十几年来才引起生物学界注意的遗传现象"。

Later, after the completion of the modern synthesis, the term neo-Darwinism would come to be associated with its core concept of evolution being driven by natural selection acting on variation produced by genetic mutation and recombination.

后来，现代综合论完成之后，新达尔文主义观念才与现代综合论的核心概念相结合。现代综合论的核心概念是，自然选择作用于基因突变和重组所产生的变异，驱动了进化。

In order to improve the efficiency of optical engine and simplify the optical architecture, a neotype color separation/recombination device based on polarization interference filter is proposed for reflective LCOS projection display in this paper.

为了提高光引擎效率并简化结构，我们提出一种适用于反射式LCOS投影显示系统的新型高效分／合色器件——偏振干涉滤光片。

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.
