查询词典 fragments

Four groups of oligonucleotides were successively cloned in pMD18-T vector to obtain four large fragments. Ligation of these four fragments resulted in a cloned DNA MgE717 coding for the 29～268 amino acid region of gE. Sequencing result showed that there is a mutation at 255 amino acid, Asn instead of Asp.

分四段分别合成，基因拼接得到了改造后的基因片段MgE717，经测序，除了在gE基因+763位核苷酸处存在一碱基置换，导致第255位的氨基酸残基由Asp突变为Asn，其余的序列与PrV鄂A株gE基因的氨基酸序列相符。

It is not one of Bolao's most successful digressions, but it is an excellent metaphor for 2666 itself:"Images with no handhold," the professor says of those ruined pages,"images freighted with all the orphanhood in the world, fragments, fragments."

这并不是波拉诺最成功的画外音，但它却是《2666》自身的最佳隐喻："无法携带的画面"，教授形容那些已经被侵蚀的图表，"支离破碎的画面，碎片，全是碎片"。这是小说的画外音，也是小说的救赎。

An enriched PCR fragments with less complexity were obtained and mainly expressed in the denervated hippoampus After cloning into the plasmid vector, 46 clones were initially screened and subjected to autosequencing By comparison with the EMBO gene databases, 21 gene fragments of different types were obtained with 11 similar to genes of known function and 10 similar to ones of unknown function It is inferable that the altered gene expressions of hippocampus following the entorhinally denervation may underlie the specfic reinnervation and the formation of synapses by transplanted entorhinal neurons with host neuropil within the denervated target areas.

初步挑选出的46个转化后的阳性克隆，经点杂交筛选和基因序列分析，与Gene Database同源性比较后，得到21种基因片段，其中功能已知的有11种，功能未知的有10种。结果表明海马在去内嗅皮层后某些基因表达的改变，这可能是移植胚胎内嗅皮层神经细胞轴突特异支配去神经靶区和重建突触联系有关。

She took a cup of strong green tea, and a few delicate fragments of toast the next morning with the same air of quiet relish common to condemned creatures who eat their last meal, while the gaolers look on to see that they do not bite fragments off the crockery, or swallow the teaspoon, or do any other violent act tending to the evasion of Mr. Jack Ketch.

第二天早晨她喝了一杯浓浓的绿茶，吃了几片精致的烤面包，津津有味，神色安详，被判处死刑的人们吃最后一餐时往往是这种神情，狱卒们倒从旁看守着他们可别从陶器上咬下几片，或吞下个茶匙，或做出其他暴力行为，借此逃避绞刑吏这一关。

Methods Specific SSU rDNA fragments from nuclear DNA of five Leishmania species and isolates were amplified by PCR. The amplified DNA fragments were cloned into pGEM R-T Easy vector.

在所选用的32条随机引物中，线粒体DNA共扩增出154条片段，其中以休眠细胞线粒体DNA为模板扩增出19条特有片段，以营养细胞线粒体DNA为模板扩增出25条特有片段，两者有29％的差异。

Objective To study the relationship between DNA fragments in ENV gene of SIVmac and viral replicating ability. Methods Reciprocal recombinants were constructed by replacing the clonable DNA fragments of ENV region of the nonpathogenic SIVmac142 clone with the pathogenic SIVmac 239 clone.

猴免疫缺陷病毒(simian immunodeficiency viruses SIV)是一组在致病性和毒力方面具有多样性的灵长类动物病毒，其中，SIVmac239克隆感染的猴表现为与人类AIDS相似的疾病，称之为致病株，而SIVmac142克隆仅引起猴发生病毒血症，不发生临床综合征，称之为非致病株〔1〕。

The result of sequence analysis indicated that the length of cDNA and DNA fragments of Lectin gene and the length of cDNA and DNA fragments of Pectate Lyase gene were 508 bp,575 bp,1,316 bp and 1,858 bp respectively.The DNA fragment of Lectin gene had a intron,whose length was 67 bp .The DNA fragment of Pectate Lyase gene had 3 introns,whose lengths were 90 bp,83 bp,and 370 bp respectively. All these four introns sequences followed the rule of GT-AG.
