多线染色体 meaning in English
multineme chromosome
polytene chromosomes
polytenic chromosome
Examples
- The polytene chromosomes found in the salivary gland cells are among the largest chromosomes known today .
唾液腺细胞中的多线染色体是目前已知的最大染色体之一。 - 1 , the histone deacetylase inhibitors were used to feed the larve of the fly , and then the polytene chromosomes were observed under the microscope . the results indicated that the histone deacetylase inhibitors had effects on the morphology of the polytene chromosomes . it is suggested that the acetytion has effects not only on the molecular interaction but also on the structure of the chromosomes
得到的主要结果和结论如下： 1 ，通过用去乙酰化酶抑制剂处理果蝇幼虫，观察果蝇多线染色体在热休克基因处的形态变化，发现去乙酰化酶抑制剂介导的乙酰化水平的升高可引起染色体结构的显著变化，推测乙酰化修饰不仅影响分子间的相互作用而且还可以影响染色体的高级结构。 - 6 , we used gcn5 and rpd3 genes as probes to detect the homologous sequences in drosophila melanogaster by fluorescence in situ hybridization ( fish ) . this work has provided useful information for the localization and cloning of related histone acetyltransferase and histone deacetylase genes in drosophila melanogaster
6 ，利用己获得的酵母gcns和rpd3基因为探针，对果蝇多线染色体进行原位杂交实验，试图找出与gcns和rpd3基因同源的基因片段。为今后克隆和分离果蝇中与乙酞化和去乙酚化相关的基因奠定基础。
