染色质的

Histopathology of the hyperpigmented lesion revealed increase of melanin in the basal layer, pigment incontinence and amorphous eosinophilic masses stained positive as with Congo red in the papillary dermis.

色素沉著的病灶其组织病理显示在基底层有黑色素的增加，乳突状真皮出现色素失调和均质的嗜伊红性块状物质沉积，且以刚果红染色呈阳性反应。

The cytomorphological changes of K562 cells were observed in the electron microscope.Results RRTJ at the concentration of 1μL/mL expressed obviously inhibitory effect on the growth of K562 cells.The inhibitory effect at the concentration of 2μl/ml went up to its highest at 83.4%.RRTJ showed virulence to K562 cells.The karyon changed because of RRTJ attending.

结果 每mL培养液含1μL刺梨汁即对肿瘤细胞增殖有明显的抑制作用，每mL培养液含2μL刺梨汁抑制作用达到最大，为83.4%，再加大剂量抑制作用无明显升高，各种剂量的刺梨汁对细胞均无毒性，刺梨汁的加入使得细胞体积明显变小，细胞核形态发生改变，异染色质增多。

There appeared prominent signals on pericentric regions of all the other chromosomes besides chromosome 4. The signals were strong on most of the chromosomes and weak only on one chromosome pair.

这一克隆除在第4染色体近着丝粒区显示明显的信号外，其它染色体的近着丝粒区同样具有信号，多数染色体为强信号，仅1对染色体信号较弱，还有3对染色体具有像着丝粒两侧异染色质块(pericentric heterochromatin block)的信号，中间有一个缢痕。

Dot1 binding to chromatin occurs normally in the absence of H2B-K123 ubiquitylation, suggesting that ubiquitylation does not regulate enzyme recruitment but does regulate the processive activity of the histone methyltransferase.

Dot1结合到染色质通常出现在H2B－K123没有泛素化的状态，暗示泛素化并不调节酶的募集，但调节组蛋白甲基转移酶后续作用的活性。

RDNA in different positions existed in either condensed or uncondensed forms. Nucleolus-associal-ed chromatin outside nucleolus extended in the periphery of FC via channels in the nucleolus.

不同位置的rDNA成分都具有集缩和解集缩两种形态结构，核仁外的核仁伴随染色质经过核仁通道进入核仁，沿FC周边排列，与其中的DNA相连。

Chromatin unwraps in places where it shouldn't, as sirtuin guardians work overtime putting out fires around the genome, and the unwrapped genes never return to their silent state.

染色质unwraps的地方，它不应该，因为sirtuin监护人加班扑灭火灾的基因组，并打开基因从来没有返回他们的无声状态。

Moreover, the distinguised advantages of applying the bivalents instead of somatic chromosomes to carry out the studies of fish gene mapping were discussed in details, and a few of new tentative ideas about how to develop the gene mapping in fish deeply were primarily postulated and theoretically analyzed in this paper.

此外，还详细讨论了以鱼类二价体替代体细胞染色体开展基因定位研究的突出优点与必要性；地高辛标记原位杂交技术和PRINS技术的特色与应用潜力；染色质风韵与等同区等新概念；以及如何深入开展鱼类基因定位研究的新设想。

The function of plant genomes depends on chromatin marks such as the methylation of DNA and the post-translational modification of histones.

植物基因组的功能依赖于染色质标记，诸如DNA的甲基化和组蛋白的转录后修饰。

Furthermore, the abnormality of PARP's activity and chromatin structure in leukemia cells was detected. Possible significance of this result was discussed.

在此认识的基础上，初步研究了PARP在白血病细胞中的异常活性，白血病细胞染色质结构异常及其可能的意义。

The other one was cultured for retinal progenitors. Then neurosphere-like cell clusters were observed by TEM.

结果：在胚胎5月的人视网膜神经上皮层细胞的细胞核内出现了大量的异染色质。

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。
