染色质的

Heterochromatin has shown to be composed largely of short repeated polynucleotide sequences.

异染色质大部分是由短而重复的多核苷酸序列所组成的。

The changes included that the protrusions on the cell surface diminished, myofilaments and pinosomes in the myoepithelial cells of grade Ⅱ,Ⅲ atypical hyperplasia decreased, and the irregularity of the nuclear morphosis and the increase of nuclear heterochromosome were found.

乳腺不典型增生时肌上皮细胞数目增多，排列紊乱，电镜下可见：①细胞表面的棒状突起消失；②Ⅱ、Ⅲ级不典型增生时胞浆内的肌微丝和吞饮小泡减少；③细胞核增大，不规则，异染色质增多。

Results Of 52 AL patients, 28 were patients with diploid, 22 were patients with heteroploid and 2 were patients with suspected heteroploid. The prevalence of heteroploid in AL patients was 42.3%.

恶性肿瘤的重要特征之一就是细胞无限制地增生，在形态学上表现为细胞核增大，核内染色质增多，这是核内DNA不断复制的结果。

Results1.In diabetic rats,the pathological change of the retinal structure displayed the decrease of the retinal ganglion cells\' number,and the signs of the apoptosis in different degrees could be found in the altrastructure of retinal neurons,including:cell shrinkage,chromatin margination and nuclear collapse,and so on.

结果1。随糖尿病大鼠病程延长，逐渐出现视网膜神经节细胞数量减少、细胞排列紊乱的病理改变，透射电镜下可见视网膜神经细胞出现胞浆浓缩、细胞体积缩小、染色质边聚、细胞核固缩、断裂等不同阶段的凋亡征象。

In addition, ChIP assays showed that NaBu treatment increased the binding of Sp1 to ALAS2 gene promoter.

染色质免疫沉淀实验还发现NaBu的处理能增加ALAS2基因启动子上Sp1因子的结合。

Cells from control embryos consist of a nucleoid core with zero or minimal DNA migrating into the tail region, while cells from treated embryos with much more DNA migrating into the tail region.

染色质浓缩边集和分割是细胞凋亡的典型形态学变化，绝大多数凋亡细胞在电泳时会出现DNAladder，也是DNA片段化检测中较传统的方法。

In human interphase nuclei Y-chromatin is studied by quinacrine dihydrochloride stain and by fluorescent light source for microscope, both of which are made in Shanghai China.

用国产阿的平染料和显微荧光光源研究了人间期核内的Y染色质。

This is the first fish sex chromosome specific repetitive DNA sequence which was found in China so far.

将上述片段的探针对刺鳅染色体进行FISH分析后，结果显示，其中RMX6对于X染色体是特异的，其杂交信号仅限于X染色体上异染色质区。

Chromatin has been set shrunk to thin linear structure, each chromosome and the nuclear membrane through the attachment plate connected to increase the size of this nucleus, nucleolus rate as well.

染色质已集缩成细长的线状结构，每条染色体通过附着板与核膜相连，此期核的体积增大，核仁也较大。

In chromatin immunoprecipitation assay, we found that CBP/p300 could acetylate histones on IL-5 promoter, resulting in increased accessibility of the open chromatin to the transcriptional machinery and therefore promoted gene transcription.

这样产生一个相对开放的染色质构型，从而促进转录机器与DNA的结合，进而促进转录。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.

扫描电镜观察多杀性巴氏杆菌细菌幽灵和菌落形成单位评价遗传灭活率。
