Along the length of the uncoiled chromosomes are beadlike structures called nucleosomes, highly organized aggregations of DNA and histones.

解聚后的染色体呈现一系列核小体相互连接的串珠状结构，核小体是由 DNA 和组蛋白高度有序的结合形成的。

There were on unique different protein observed in flag leaf at different development stage; but unique different protein were found in young spike at uninucleate microspore stage and non-1B/ 1R type male sterile lines lack a 17kD polypeptide compared with maintainers; at binucleate microspore stage and non-1B/ 1R type male sterile lines increase 17kD polypeptide compared with maintainers.

利用SDS-PAGE凝胶电泳技术对采用丙酮沉淀法提取的K型，C49S型和YS型小麦不育系和保持系旗叶小穗发育的单核期和二核期中的可溶性蛋白进行比较后发现，非1B/1R类K型不育系732A在小穗发育的单核期比同时期相应保持系732B少1条分子量为17kD的多肽，在小穗发育的二核期比同时期相应保持系732B多1条分子量为17kD的多肽。

Polyhedrin and virion, which were isolated and purified from Agrotis setegum nuclear polyhedrosis virus, are administered to 3-instar Heliothis armigera larvae with Heliothis armigera nuclear polyhedrosis virus. Both polyhedrin and virion could increase mortality of H. armigera larvae, shorten half mortality time and decrease half mortality concentration.

对黄地老虎核型多角体病毒的多角体蛋白和病毒粒子组分进行分离纯化，分别与棉铃虫核型多角体病毒混合感染三龄棉铃虫幼虫，发现此二种组分均能够提高棉铃虫幼虫的死亡率，缩短半致死时间，降低半致死浓度。

The 75kD polypeptide in SDS-PAGE about all protein in eight isonuclear alloplasmic and allonuclear isonuclear male-sterile lines had been found keeping close with the male sterile.

对8 个同核异质、同质异核不育系和相应保持系进行花药全蛋白SDS-PAGE，发现了75kD多肽与雄性不育关系密切。

In this paper, Attacus ricini nuclear polyhedrosis virus was studied. The molecular weight and pi of polyhedrin and structural polypeptides were determined by vertical slab SDS-PAGE and thin-layer isoelectrofocusing electrophoresis. The restriction pattern of ArNPV DNA was assayed by 5 restriction endonucleases.

本文较为系统的研究了蓖麻蚕核型多角体病毒(Attacus ricini nuclear polyhedrosis virus，简称ArNPV)形态特征和生化特性，并预测了多角体蛋白的二级结构，为开发利用蓖麻蚕核型多角体病毒这一生物资源提供了理论参考。

The centrosome is the classical site of microtubule nucleation and is thought to be essential for axon growth and neuronal differentiation--processes that require microtubule assembly.

中心体是微管核化的经典位置，并且轴突生长和神经分化都需要微管蛋白的组装核化。

ThenWestern blotting were applied to detect nuclear EGFR and cytoplastic EGFR in Caski cellswhich showed hight level expression of EGFR after radiation.

第四部分辐射对宫颈癌细胞EGFR核转运的影响EGFR家族成员直接转运入核调节靶蛋白和靶基因的表达和活性是新近发现的EGFR家族传递信号的新途径。

FPNl showed the highest expression in medial habenular nucleus, but no difference was found among three periods of age.

另外，FPNI在缓内侧核表达最高，疆内侧核毗邻第三脑室，可能是脑内的铁代谢中心之一。 PC12细胞在低铁状态下FPNI mRNA和蛋白表达增高，高铁状态下FPNI表达降低。

Some evidence indicates that the combination of extrinsic, intrinsic and genetic factors all play a role to cause the disc degeneration, with a progressive decrease in proteoglycan content leading to dehydration of the nucleus pulposus, and Type Ⅰ collagen begins to appear in the matrix, the ratio between Type Ⅰ and Type Ⅱ increases. All these cause the swelling pressure, disc height and the disc load bearing ability decrease. The disc progressively herniate and cause radiculopathy and myelopathy.

内因、外因及遗传方面的诸多因素导致椎间盘逐步退变后，其实质就是基质中蛋白多糖的减少，含水量降低，Ⅰ型胶原出现在基质中，Ⅰ、Ⅱ型胶原的比例明显上升，髓核呈纤维样改变，导致椎间盘的膨胀压降低，承重能力下降，椎间高度降低，椎间盘承受的重力不能平均地向各方向传递，致使纤维环疲劳、破裂、髓核突出，造成脊髓或马尾神经受压，引起严重后果。

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