查询词典 polytene

The research was ultimately possible thanks to the unique composition of the fruit flies' polytene cells -- giant, multistranded chromosomes with hundreds of sets of the genome instead of the usual two sets in conventional cells.

这项研究可能最终还要感谢果蝇与众不同的染色体组成--巨大、多链状染色体，和一般细胞两套染色体不同，果蝇染色体有数百套之多。

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。

Methods Mature larvae of blackflies were selected, dissected and shelled out salivary glands. The traditional method was improved, and the clear polytene chromosomes slices were prepared after the use of new staining fluid, flush fluid and cleaning fluid.

选用经Carnoy's液固定的蚋成熟幼虫进行解剖、剥离唾腺，对传统蚋类唾腺多线染色体制备方法进行改进，包括改良染色液，使用冲洗液、背景净化液等新制剂和新步骤并得到清晰的蚋唾腺染色体图形。

The protocol is summarized in Figure 18.16. A radioactive probe representing a gene (most often a labeled cDNA clone derived from the mRNA) is hybridized with thedenatured DNA of the polytene chromosomes in situ. Autoradiography identifies the position or positions of the corresponding genes by the superimposition of grains at a particular band or bands.

如图26.15所示为此过程草图：一个放射性探针代表一个基因（常是一个从mRNA中克隆得到的cDNA），它与原位多线染色体的变性DNA杂交，放射自显影仪可通过叠印特定纹带的纹理来识别应答基因的位置。
