果蝇

Furthermore, ed embryo exhibit extra C.N.S. and P.N.S. neurons. Ed also serves in Drosophila eye development and mesothoracic bristle development. Photoreceptor cells of the ommatidium and bristles are sensory nerves. We suggest that Ed might meditate the development of the nervous tissues.

此外，ed mutant胚胎有过多的中枢以及周边神经细胞生成，Ed亦参予在果蝇复眼发育以及背板刚毛的形成过程，果蝇复眼感光细胞以及刚毛均为周边神经细胞，显示Ed对於神经细胞生成具有某种程度的影响。

We also use linear and polynomial fit to analyze their distribution trends and differences among chromosomes and among different kinds of sequences.

果蝇染色体参数X值是由D1和D2值共同决定的，但果蝇染色体的编码序列参数X分内含子序列相比，分布没有趋同性。

Auraria from $ areas in China and some from Japan, it was.found that in all of the species, the homologous chromosomes were in various degree of synapsis,while the nonhomologes were distributed at random in the nucleus.

对采自北京、上海等7个地区及来自日本的金色果蝇I Drosophila auraria）和金色果蝇III的三龄幼虫的脑神经节进行核型分析。

In this exper iment, we took the advantage of RNAi technique, microinjected tinman and wingless dsRNA into the early embryos in Drosophila respectively and got these two genes' RNAi phenotypes, which were very similar to that of their mutant, showing heart tube defects or no heart precursors formation.

实验运用RNAi技术，分别将tinman和wingless的dsRNA注入果蝇的早期胚胎，得到了这两个基因的dsRNA干扰表型，与两个基因的突变体表型非常相似，都表现为果蝇心脏前体细胞不能形成或心脏管缺失。

Methods Andrias davidianus meat was separated into three groupsaccording to its dosage(4%,2% and 1%,respectively),and was put into different cultures.The pure culture was made as control group.

方法以大鲵肉浆，分别按占培养基的4%，2%，1%含量，加入到基础培养基中，并以基础培养基为对照组，观察对果蝇寿命、生殖能力、飞翔能力、耐寒能力的影响，测量果蝇体内超氧化物歧化酶、脂褐素活性的变化。

FlyBase includes data on all species from the family Drosophilidae ; the primary species represented is Drosophila melanogaster .

包含果蝇科所有种类的资料，其中以黄果蝇为主。

The goals of the Drosophila Genome Center are to finish the sequence of the euchromatic genome of Drosophila melanogaster to high quality, and to generate and maintain biological annotations of this sequence.

柏克莱果蝇基因组计画：本中心的目的在於完整定序黄果蝇常染色体上的基因，并进而对这些序列进行分析，以找出相关的基因功能。

The goals of the Drosophila Genome Center are to finish the sequence of the euchromatic genome of Drosophila melanogaster to high quality, and to generate and maintain biological annotations of this sequence.

柏克莱果蝇基因组计画的目的在於把黑腹果蝇常染色体上的基因组序列完善到高品质，以创建并维护该序列的生物学注解。

Berkeley Drosophila Genome Project. The goals of the Drosophila Genome Center are to finish the sequence of the euchromatic genome of Drosophila melanogaster to high quality, and to generate and maintain biological annotations of this sequence.

柏克利果蝇基因组计划的目的在于把黑腹果蝇常染色体上的基因组序列完善到高质量，以创建并维护该序列的生物学注解。

The main results and conclusions are as followings.1, The histone deacetylase inhibitors were used to feed the larve of the fly, and then the polytene chromosomes were observed under the microscope.

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。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
