查询词典 chromosome

Due to the breakthrough of stained technology in 1970s, the band-pattern of chromosome provides material visual information for cytogeneticist, then analyses the composition of genome in a cell and measures the features of the equipments for karyotyping.In order to meet the demands of clinical hospital, a chromosome analysis system based on PC is developed.

由于70年代标本染色技术的突破(取代了此前的均匀染色方法，产生了染色体的带型特征)，染色体的带型模式为细胞遗传学家提供了实质性的视觉信息，从而可以进一步分析细胞的基因组的合成以及进行自动核型分类仪器中的特征测量。

DNA refers to deoxyribonucleic the acid deoxyribonucleic acid (chromosome and gene constituent) the deaeration nucleotide high polymer, is the chromosome principal constituent.

DNA 指deoxyribonucleic acid 脱氧核糖核酸(染色体和基因的组成部分)脱氧核苷酸的高聚物，是染色体的主要成分。

Chromosome Microdeletions And Recurrent Pregnancy Loss - UroToday.com - Dewan and colleagues conducted a study which demonstrated that the prevalence of y-chromosome microdeletions was higher in patients undergoing evaluation for recurrent pregnancy loss (n=17) compared to 18 fertile couples without pregnancy loss and 10 infertile men.

染色体微缺失、反复流产-urotoday.com-伊斯兰德和同事所进行的一项研究表明，艾滋Y染色体微高于患者进行评价反复流产(17例)则为18和10失去肥沃不孕夫妇怀孕没有男人。

Fig 1 The results of two color FISH A:Normal sperms(a sperm nucleus with a red fluorescence domain was X sperm, and with a green fluorescence domian was Y sperm);B:Numeric chromosome abnormal sperm two green fluorescence domains within the same sperm nucleus which may be classified in Y disomic sperm or diploidy sperm, in the case of hybridization with two probes, one euchromosome specific and the other sex chromosome specific, this sperm could be discriminated as disomic or diploidy sperm

图1 双色荧光原位杂交结果 A：正常精子(精子头部有1个红色荧光信号者为X精子，有1个绿色荧光信号者为Y精子)；B：染色体数目异常精子两个绿色荧光信号同在1个精子核内，可为Y双体精子或二倍体精子，若用1条常染色体探针和1条性染色体探针进行双色荧光原位杂交，可以区别该精子属Y双体精子或二倍体精子

The decomposition of chromosome was a main problem in construction of BAC library. DNA discompose would be avoided or decreased by adjustments of component and pH of chromosome extraction buffer or pre-electrophoresis for 6-8h before digestion. Identification of inter-species hybrids was a necessary step for creating a new germplasm. Two samples were selected from offspring of hybridization and backcross of a cross between cabbage and Chinese cabbage.

鉴定种间杂种是利用远缘杂交创造新种质时的一项重要工作，本研究运用细胞核DNA含量流式测定技术，对甘蓝和白菜杂交及回交各世代的DNA含量进行检测，以监控遗传物质在不同材料间的流向，并从回交二代植株群体中筛选了两个材料，具有和白菜差异不显著的DNA含量，可推断其为核质杂种。

The wild wheat with its small 14-chromosome grain s to make Emmer, a larger 28-chromosome grain that scattered in the wind.

野生小麦属飘散在风中的有14个染色体的小颗粒，它与具有14个染色体的假升麻草杂交变成了二粒穗小麦，即飘散在风中具有28个染色体的较大颗粒，

The wild wheat with its small 14-chromosome gra in s to make Emmer, a larger 28-chromosome gra in that scattered in the w in d.

野生小麦属飘散在风中的有14个染色体的小颗粒，它与具有14个染色体的假升麻草杂交变成了二粒穗小麦，即飘散在风中具有28个染色体的较大颗粒，

The wild wheat with its small 14-chromosome grains to make Emmer, a larger 28-chromosome grain that scattered in the wind .

野生小麦属飘散在风中的有14个染色体的小颗粒，它与具有14个染色体的假升麻草杂交变成了二粒穗小麦，即飘散在风中具有28个染色体的较大颗粒，

Emmer crossed with another 14-chromosome goat grass to make bread wheat, an even plumper 42- chromosome grain that did not scatter in the wind, but must be planted.

它与另外具有14个染色体的假升麻草杂交便生成我们做面包的饱满颗粒，但它必须人工加以种直

The aim of study was to investigate the importance of chromosome aberration in differential diagnosis of eosinophilia and the chromosomal aberrations involved in patients with clonal eosinophilia. 65 cases of eosinophilia were collected and chromosome specimens of bone marrow cells were prepared by 24hour culture, and Gbanding technique was used for karyotyping.

为探讨染色体异常克隆在嗜酸性粒细胞增多症诊断和鉴别诊断中的意义及克隆性嗜酸性粒细胞增多症涉及的染色体异常，收集了65例嗜酸性粒细胞增多患者的骨髓标本，培养24小时，采用G显带进行核型分析。
