Crystal structures of bar-headed goose aquomet hemoglobin and greylag goose oxy Hb were determined and compared, which confirms the previous postulation that α119 mutation leads to the higher oxygen affinity of bar-headed goose Hb, but indicates that β125 mutation might also make part contribution.

通过对斑头雁水合高铁血红蛋白和灰雁氧合血红蛋白的晶体结构研究，证实了前人关于α119突变导致斑头雁血红蛋白的氧亲和性提高的假说，同时推测β125突变可能也有部分贡献。

The bacterial mutation technique is an important bacterial research technique,including traditional physical and chemical and biological method,and modern genetic mutation technique.

细菌突变技术是重要的细菌学研究技术，包括传统的物理、化学、生物学等方法及现代的基因突变技术。

Methods:Direct sequencing of PCR products was applied to study G3316A mutation in blood corpuscle mtDNA in 315 T2DM patients without relation of consenouinity and 158 normal controls from Zhejiang province. The mutation was analyzed with DNASTAR and Antheprot 5.0 softwares.

采用PCR产物直接测序法对浙江籍汉族人群中无血缘关系的315名T2DM患者及158名正常对照的外周血mtDNA进行检测，并用DNASTAR和Antheprot 5.0软件分析突变位点。

Above all, the key index of colouration mechanism of'Ralls'and bud mutation is anthocyanin content and CHI activity.Key words apple; bud mutation; coloring mechanism; bagging

综上结果，芽变与原有品种在着色机理上的关键指标是果皮花青苷含量和CHI酶活性。

Agafu 6?. 6. ISSR analysis was made in all bud mutation primary electionstrains .The primer 1S026 could identify nine bud mutation primary strains.

运用ISSR技术鉴定出了9个富士芽变初选优系，其中有5个芽变初选优系应用RAPD技术无法鉴定。

We biopsied 1-2 single blastomere from 6-8 cell cleavage stage intracytoplasmic sperm injection embryo, and using nested PCR amplified the high frequently mutation region G380R of FGFR3 gene of the single blastomere. The products of PCR were digested by restriction enzyme Bfm Ⅰ, then the digested products were detected by 10% PAGE to see whether the embryo inherted the mutation of the patient and to screen out normal embryo transfer.

活检经胞质内单精子注射(intracytoplasmic sperm injection，ICSI)授精的胚胎发育至6～8细胞期的1～2个单卵裂球，采用巢式PCR扩增单卵裂球的FGFR3基因的高发突变位点G380R区域，用限制性内切酶BfmⅠ消化巢式PCR的内扩增产物，再经10%聚丙烯酰胺凝胶电泳检测有无遗传患者的该种突变，从而筛选出正常胚胎移植。

A gene can be defined as the smallest hereditary unit capable either of recombination or of mutation. Alternatively it may be described as a unit of function, a CISTRON, which may be much larger than a unit of recombination or mutation, and controls the synthesis of a single polypeptide or a messenger RNA molecule whose genetic code is sontained within the gene.

基因是重组和突变的最小遗传单位，也可以被描述为一种功能单位———顺反子，顺反子可能比重组和突变单位大的多，它控制单个多肽的合成或合成含有遗传信息的信使 RNA 密码子。

His concept is that you use the dugs which may induce mutation as early as several months or sometimes several weeks, that's why he has to check the DNA mutations, but there are now some drugs available who are OK for 5 years. If so, why you have to worry about mutation by performing expensive DNA frequency.

Keeffe教授的概念是指如果你所使用的药物是在用药几周或者几个月后就会引起突变的话，在这种情况下就需要检测HBV DNA，而对于5年耐药率都很低的药物来说，就没有必要如此频繁地进行昂贵的检测了。

The novel mutation Y271H is the disease-causing mutation in the hereditary multiple exostoses family.

EXT1基因的Y271H杂合突变是导致该家系发生多发性外生性骨疣的致病突变。
