突变的

Results The two patients with primary dystonia were found to have the gene mutation of SCA3, the CAG repeat were 80 and 75 respectively.

结果 2例原发性肌张力障碍患者SCA3基因突变，其异常等位基因的CAG重复数为80和75；SCA1、SCA2基因无突变。

PCR-SSCP method was used to detect mutations in exons 2,3,4 of runx3 gene in the gastric carcinoma.

结果：2例胃癌标本在runx3的第3外显子发现突变，第2、4外显子未发现突变改变。

Glycin is in its highest proportion in the amino acid component, while cysteine in zero.

在39个病毒株M蛋白的221个氨基酸序列中，有18个病毒株在6个位点上发生了23次突变，突变率为2.669‰。

However, environmental mutagens can also induce mutations at undamaged sites and result in the so-called nontargeted mutagenesis.

但是环境诱变剂引起的突变也可发生在非DNA损伤部位，它被称之为非定标性突变。

The aim of this study was to investigate the risk of cirrhosis associated with genotype, precore stop codon G1896A mutation and A1762T/G1764A double mutation in the basal core promoter of hepatitis B virus.

本研究乃以前瞻性世代研究法探讨B 型肝炎病毒B、C基因型、precore stop codon G1896A 突变和basal core promoter A1762T/G1764A 双突变对於发生肝硬化的影响。

By contrast, in liquid transients, pressures and flow pattern undergo smooth transitions and transient effects are small.

与气量突变相比，液量突变引起的压力和流型变化较平缓，瞬态效应小。

Luciferase activities were measured 72 hr post-transfection. All three mutants showed higher luciferase activity than that of the wild type, and the V85I mutant showed the highest activity. This result was also confirmed by neomycin gene-containing replicons with same mutations.

荧光素酶活性在转染后72小时检测。3种突变子均显示荧光素酶活性高于野生型，V85I突变子显示最高的活性。

Objective:The purpose of the experiment was to study the carcinogenic and mutagenic effects of petroleum asphalt.

目的：研究石油沥青有无致突变和致癌作用。方法：选用大鼠经口急性毒性试验、Ames试验、小鼠经口微核试验、大鼠气管注入及兔经皮涂抹致癌试验，研究石油氧化及直馏沥青的急性毒性以及致癌和致突变作用。

But all mutant proteins have been effected on the midpoint reduction potential of FAD.

但是突变蛋白质的FAD中点电位都增加，此代表电子不易传递，也就是FAD还原受突变影响。

The mutation R778L is the most common mutation of ATP7B gene in Chinese WD patients.

经检索2790del3是ATP7B基因新突变类型。R778L是中国人最常见的突变类型。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
