线粒体

The result suggested that Silkies had several maternal ancestors. It was the result of long artificial selection in different place.2. There were 39 mutation sites in mtDNA HVS-I of 124 individuals; it could be divided into 34 haplotypes.

124个常羽乌骨鸡的线粒体D环高变区序列中共有39个变异位点，可分为34种单倍型，从中可以看出常羽乌骨鸡的母系来源类型很多，至少有六个不同的原鸡母系来源。

Silkies were the mutation type of nomal feather Wugu chicken for it had more haplotypes and shared the major haplotypes with silkies.4. The sub-species of G. g. spadcieus and G. g. jabouillee in China were at the same clade with the G. g. gallus in and around the Thailand area, but were in difference clade with G.

在中国的两个红原鸡亚种的线粒体D环高变区序列与在泰国等地分布的红原鸡亚种的此段序列差异不大，可归为一类，而与爪哇岛上分布的红原鸡亚种的此段序列差异较大。

The cell in acidic situation presented a degenerative chang-ment,such as an increased lipid drop and empty cavity in the cell plasma,a py-knotic nuclei,the dilatation of the endoplasmic reticulum and Golgi saccules,mi-tochondrial swelling the number of ribose decrease,and the ribose dissociated inthe plasma,a lot of swallowing cavity,the fibric material decreased accompany-ing with the acid being stronger.

随培养基pH逐渐下降，上述过程因受酸性阻抑而延缓，细胞增殖速度也受影响，处于酸性环境中的软骨细胞呈退行性变化，表现为细胞浆内脂质颗粒与小泡增多、细胞核皱缩、核仁浓染、内质网线粒体膨胀、核糖体数目减少，且与粗面内质网结合的少，游离在胞浆中的多。

Among them multi-types of body colour and special types of hosts are the most universal phenomena. In our experiment, methods of microsatellite primer PCR molecular marker and partial gene sequence analysis of mitochondrial DNA COⅠ-Ⅱwere used to analyze genetic diversity of two body colour bio-types (red bio-type and green bio-type) of green peach aphid from different plants and relationship between green peach aphid and host plants by separately selecting individuals of aphid from rape, Chinese cabbage and tobacco. The main results as follows: 1. Selecting An Ruisheng'method of extracting DNA from small sized insect, using this method can extract DNA well and steadily.

本文采用微卫星引物PCR 分子标记和线粒体COⅠ-Ⅱ部分序列分析的方法，分别选取十字花科植物中的甘蓝和油菜，茄科植物中的烟草，对不同寄主上桃蚜的红色和绿色两种体色生物型的遗传多态性及其与寄主植物的关系进行了研究，取得的主要结果如下： 1、选取安瑞生(2002)小型昆虫DNA 提取方法，能很好且比较稳定的提取桃蚜基因组DNA。

Ribozymes have been shown to occur in the mitochondna of eukaryotic cells and to catalyze other reactions that resemble the polymerization of RNA.

已经发现核酶在真核细胞的线粒体中存在，并且能催化其它类似RNA聚合的反应。

Before treatment,there are abundant microvtlli on the cell surface,many filoplodia on the cell rim,few of endoplasmic reticulums , Golgi complexes and mitochondrions with abnormal structure and lots of free ribosomes in the cytoplasm. The shape of nucleus is irregular with high nuclear-cytoplasmic ratio, many dark pellets of heteromatin and a few of nucleoluses in which there ar...

经1.5×10~2g/L地塞米松处理后，细胞表面微绒毛和丝状伪足显著减少或消失，出现皱褶状和小泡状结构；细胞核形规则，核质比值减小，异染色质团块减少，核仁数目减少、结构致密；细胞质中粗糙型内质网、高尔基体、线粒体数量增多，形态结构典型，游离核糖体减少，这些变化说明地塞米松改变了MGc80-3细胞的超微结构特征，具有明显的诱导分化作用。

Results From the fourth week, in diabetic rats, the contents of AGEs in plasma and the abdominal aorta increased, the relative area of α-SM-actin in the abdominal aorta decreased, the density of nucleus of VSMC increased, and mitochondria and rough endoplasmic reticules in VSMC increased.

结果 从4周起，DM大鼠血浆和腹主动脉的AGEs显著增多；腹主动脉α-SM-肌动蛋白的相对面积减小，VSMC的细胞核密度增大，线粒体和粗面内质网增多。

AIM In order to investigate the effects of pyrethroid on the cytochrome c oxidase activity of mitochondria in rat liver and brain and try to explore the mechanism of the inhibition of thyroid hormone.

目的 观察拟除虫菊酯对大鼠肝脏和脑组织线粒体细胞色素氧化酶活性的影响，初步探讨甲状腺激素水平下降的可能原因。

5 A How many protons are in a spherical mitochondrium with a diameter of 1 m at pH = 7?

在PH=7的情况下，有多少质子在直径为1 m的线粒体上。

There were a large numberof ppts located in the pollen wall during pollendevelopment (Plate II-6), suggesting that ATPaseis necessary for the construction of pollen wall.

在真核细胞中，除了线粒体和叶绿体ATP酶的功能是合成ATP外，其余部位ATP酶是水解ATP以获取能量的代谢酶(Pederson和Carafoli1987)，在生物体细胞内广泛存在。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
