In this study, we used RNA whole mount in situ hybridization to analyze the expression pattern of the dGATA-II gene in the embryonic stage, and found it expresses in the brain、central nervous system、midgut and posterior spiracles at different stages.

由於过去研究，使dGATA-II基因结构已被清楚了解，本论文承续前者，对dGATA-II转录因子在果蝇胚胎时期，促使细胞发育达到特定形态的功能进行探讨。

Its expression specificity began at the somites stage, mainly in the nervous system of the head.

Nspc1/pcgf1是在果蝇及哺乳动物中广泛表达的一个多梳家族基因。

"With mice and fruit flies we were able to eliminate the loss of short-term memory," Ropers, 62, is quoted saying in the German newspaper, which has dubbed it the "world's first anti-stupidity pill."

现年62岁的罗普斯说：&在老鼠和果蝇身上的药物试验表明，我们研制的药物已经能够减少短期记忆的遗失。这种药可谓是世界上第一种'抗愚蠢'药。&

Here, we show that Drosophila condensin II promotes disassembly of polytene structure into chromosomal components.

在这里，作者展示了果蝇凝聚蛋白II能够促进染色体组成中多聚结构的分解。

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。

By the method of SDS-PAGE, the main proteins of nuclear, matrix in salivary gland were proteins of 67kd, 66kd, 43kd, 38kd and 35kd Comparing the NHP composition of the nuclear matrix to that of the polytene chromosome, it can be seen that the nuclear matrix and the polytene chromosome shared many common NHP components, such as 43kd, 38kd and 35kd proteins.

通过SDS-聚丙烯酰胺凝胶电泳看到，果蝇唾腺细胞核基质的主要蛋白成份为67kd、66kd、43kd、38kd及35kd等多肽。与多线染色体骨架的蛋白成份比较，发现它们共同具有43kd、38kd及35kd等蛋白质。

The purpose of this laboratory is to train undergraduate students with practical genetics, including the basic principles of genetics, inheritance of pea traits, root tip chromosomes, Drosophila salivary polytene chromosomes, meiosis, statistical methods, bacterial antibiotic resistance, plasmid isolation, restriction, and gel electrophoresis, blood type, and human genetics.

遗传学实习 1 必陈福旗，戴国兴本课程之目的，在使学生透过实际操作与试验，了解遗传学之原理，实验内容包括：碗豆七个性状遗传，植物根尖染色体观察，果蝇唾腺染色体，减数分裂，统计方法，细菌抗药性，质体之抽取及限制酵素切割及电泳分离，血型，人类遗传。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
