染色体基因

Later research showed that this duplication,inserted within the same chromosome,harbors an additional copy of a gene involved in making a nerve cell's protective sheath.

后来的研究表明，这种重复序列插入到同一染色体中，并潜藏了一个额外的拷贝在一个编码神经细胞保护鞘的基因中。

Oocyte samples from one group were collected to detect the presence and integration of HBV DNA within cells and chromosomes using PCR, Southern blot, dot hybridization and fluorescence in situ hybridization. The female animals from another group were mated with their normal males, respectively. Their zygotes, 2-cell embryos were collected to detect the integration of HBV DNA in the female pronuclei of zygotes and the replication and expression of HBV genes in the 2-cell embryos using FISH, RT-PCR and immunofluoresence assay.(1) PCR detected positive bands in the tested oocyte samples fromgoldon hamster and mice. Southern blot revealed clear hybridization signals in PCR products.

研究用金黄地鼠和小鼠建立实验动物模型：将卵巢内注射HBV DNA的实验动物分成两组，一组注射后进行超排卵，收集卵巢和输卵管的卵母细胞，用PCR、Southern杂交，斑点杂交和荧光原位杂交(fluorescence in situ hybridization、FISH)检测HBV在卵母细胞内的存在和染色体上的整合；另一组超排雌鼠与正常雄鼠合笼，收集受精卵和2-细胞胚，用FISH、RT-PCR和免疫荧光检测技术分别研究HBV基因在受精卵雌原核上的整合以及在2-细胞胚中的复制与表达。

There are many documents indicated many kinds of pathogenic bacteriums have the ability to lead latent infection, maybe which is related with the genome conservatived TA system of prokaryote.The TA system is made up of toxin and antitoxin and is concerned to be quality control system of prokaryote.

研究结果提示，很多不同种属的病原菌都具有形成潜在感染的能力，可能与原核生物染色体基因组上保守的TA系统有关，其主要由毒素和抗毒素位点组成，被认为是原核生物基因表达的质量控制系统。

The parental origin of extra chromosome 21 was determined by comparing genotypes of probands with their parents.

根据患者及其父母基因型的比较来确定21号额外染色体的双亲起源。

The fruit fly Drosophila melanogaster is an important model organism in research fields of genetics and developmental biology due to the advantages of easy to breed and to get enough embryos in the laboratory, short life cycle, having large polytene chromosomes, and etc. It has made great contributions to the development of modern life science.

果蝇由于具有容易饲养、产卵多、生命周期短以及具有粗大的多线染色体而便于进行基因定位等优点，已成为遗传学和发育生物学等研究领域中重要的模式生物之一，对现代生命科学的发展作出了突出的贡献。

Based on this result, it is concluded that the change of acetylation level at the loci of hsp, mediated by histone deacetylase inhibitors, exertsimportant functions in hsp gene transcription.3, After immunolabeling with anti acelated-lysine monoclonal antibody on the polytene chromosomes of heat shocked flies, fluorescence signals were detected at the hsp loci.

3，利用抗乙酰化赖氨酸的单克隆抗体对热激处理后的果蝇幼虫多线染色体进行的免疫荧光实验结果表明在热休克诱导的hsp70基因的表达中存在乙酞化修饰。

Objective:To explore the relationship between D44v6 expression, p53 gene mutation, cell ploidy and colorectal metastasis.

目的：探讨大肠癌CD44v6表达、p(53)基因突变和染色体倍性与大肠癌转移之间的关系和作用机理。

We then patch these genetic elements in the plasmid and insert it back into the bacterium, he added.

我们能够修改在质粒中的这些基因单元然后把它重新插入细菌的染色体中，他补充说。

Recent advances have allowed nucleosome dynamics on promoters to be studied in real time, dramatically changing how we think about gene regulation on chromatin templates.

目前的进展已经能够实时地监控启动子上核小体的动力学改变，戏剧性地改变了我们对染色体上基因调控的认识。

Genes line up on strand called chromosomes in cells.

基因以排列的形式存在于细胞中的一种名叫染色体的物质中。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
