查询词典 x chromosome

The apical bud of Celosia cristata was immersed in 0.05%, 0.1%, 0.15% and 0.2% colchicine solutions for 12 h, 24 h, 36 h, 48 h respectively and the chromosome numbers of the root tip cells in the regenerated plantlets were examined, which showed that the treatment with 0.15% colchicine solution for 36 h would be the best combination that the polyploid rate could reached 23.3%.

采用浸泡法将鸡冠花营养芽在0.05%、0.1%、0.15%和0.2%不同秋水仙溶液浓度下分别处理12h、24h、36h和48h，并对诱导处理后获得的再生植株进行鉴定，得出以0.15%秋水仙素溶液浸泡36h为诱导多倍体的最佳处理组合，诱导率达23.3%。

Objective:To examine the effects of ECRG2 in centrosome amplification and chromosome instability.

目的：非整倍体是肿瘤细胞的典型特征，是人类肿瘤染色体不稳定性的普遍形式。

Thus, centrosome abnormalities can lead to chromosome instability and cancer.

当中心体功能出现障碍时，往往伴随染色体分离异常，从而导致癌症的发生。

It is of great important to study the cercospora leaf spot resistance of sugar beet M14 which has No. 9 chromosome of Beta corolliflora Zoss in addition. After spraying with the Cercospora beticola Sacc.

甜菜M14品系由于附加了一条野生白花甜菜第9号染色体，因此，研究其是否具有抗病性以及抗病程度的强弱具有十分重要的意义。

The chorionic villi cells may be used for chromosome analysis or other genetic testing.

这些绒毛膜绒毛细胞可被用于染色体分析或其他遗传学测试。

Chromogenic In situ hybridization is used to detect specific nucleic acid sequences in tissue, cell, or chromosome aberrations.

显色原位杂交法可用于对组织/细胞或染色体畸变中的特异核酸序列进行检测。

It is thought to represent and area where the chromosome is relatively tightly coiled.

它被认为是染色体相对紧密折叠的区域。

Each chromosome is made up of a tightly coiled strand, a molecule of DNA.

每一个染色体是由一个紧紧缠绕链，一个分子的DNA 。

Firstly, the recombinant engineering technology related vaccine preparation was set up, including: 1. the gene knock-out based on linear DNA target molecular in vivo; 2. the selection and counterselection technology of exogenous gene knock in definite site on chromosome; 3. the Gap-repair clone technology in vivo; 4. the recombination technology of single-chain DNA and the overlapping primer; 5. Set up the new selection and counterselection technology of neo-E.

本研究首先建立与疫苗制备相关的重组工程技术包括：①基于线型DNA打靶分子的大肠杆菌体内基因剔除技术，②选择与反选择外源基因定位敲入染色体上特定位点技术，③Gap-repair体内克隆技术，④单链DNA重组技术和重叠引物介导的DNA重组技术，⑤建立&抗生素-酶切位点&选择反选择技术新技术。

It is expected that hyg would be integrated stablely into the chromosome along with insert while spc/str would be lost during the second cross-over. Gene replacement through these two flanking sequences will result in the susceptibility of the transformants to phage φHAU3, which provides an enrichment for desired transformants by counterselection.

预期在携带有大插入片段的基因置换YAC分子进入野生型变铅青链霉菌后，YAC分子将通过1.4kb或1.0kb片段与染色体发生同源单交换，继而发生同源双交换，hyg连同大插入片段一起稳定地整合到染色体上，而spc／str丢失，从而导致菌株Hyg〓Str〓的表型。

Alternatively, the con- trollers can use the synchronous rectifier itself or loss- less inductor current-sensing methods to provide overload protection with lower power dissipation.
