末端的

In contrast with the well-known interactions of the minus ends with the centrosome, little is known about the termination site of the noncentrosomal minus ends.

中心小体负末端间的相互作用是总所周知的，而人们对分散负末端间的相互作用却知之甚少。

We have investigated the conformational features of four short peptide fragments of Staphylococcal nuclease by homonuclear two-dimensional NMR and circular dichroism with a view to examining the early events in the folding process of SNase.

Methods The model of subacutely aging rats were made by injecting Dgal into the rats, abdominal cavity continually. After lavaging HSWY, the apoptosis rate and the levels of Fas and FasL mRNA were measured by TUNEL and RTPCR; the expressions of Fas/Fasl protein were detected by SP immunocytochemistry.

采用D半乳糖连续腹腔注射致亚急性衰老大鼠模型，同时以何首乌饮灌胃作为延缓衰老组；造模后应用脱氧核糖核苷酸末端转移酶介导的缺口末端标记法检测各组大鼠卵巢细胞凋亡情况；测定各组Fas和FasL的信使核糖核酸水平；SP免疫组化法检测卵巢细胞Fas和FasL蛋白的表达情况。

A series of UV curable waterborne hyperbranched polyester s with different acid/amine terminal rate,which contained -OH?-COOH and methacrylic chain end groups,and were partly neutralized with thertiary amine,were synthesized from trimellitic anhydride,epichlorohydrin,glycidyl methacrylate and triethylamine.

以偏苯三酸酐、环氧氯丙烷、甲基丙烯酸缩水甘油酯、三乙胺合成了末端羧基与氨基不同比例的一系列可UV固化的高支化聚酯，研究了末端官能团对合成产物水溶性、粘度以及凝胶转化率的影响。

In addition, because the trajectory error of the end effector is increasing when the joints are motivated by untuned joint signals, a tuning method of joints is proposed to reduce the trajectory error. The effectiveness of this method is proved in the experiment.

另外，为解决实验中发现的机器人末端轨迹误差较大的问题，根据实验特点设计了机器人关节角输入补偿策略，提高了实验中机器人末端轨迹的跟踪精度。

"Feedback inhibition:A cellular control mechanism in which an enzyme that catalyzes the production of a particular substance in the cell is inhibited when that substance has accumulated to a certain level, thereby balancing the amount provided with the amount needed."

&反馈抑制：当某生化反应系列的末端产物到达某一固定的水平时，该末端产物对控制该系列生化反应早期阶段的某个酶产生了抑制作用，从而平衡供给和需求量。&

Extracting exonic sequences directly from genomic sequence is difficult, but ESTs have provided a convenient means of accessing them. An expressed sequence tag is part of a gene that results from sequencing a portion of a cDNA clone that was generated from an mRNA.

从mRNA来源的cDNA文库中随机取出一个克隆，从5'末端或3'末端对插入的cDNA片段进行单向测序，所获得EST为我们研究基因表达提供了方便快捷的手段。
