查询词典 nucleotide

Up-regulated proteins under salt stress include an ABC transporter permease, glycerol-3-phosphate permease, pyrimidine nucleotide transporter, formate dehydrogenase, and down-regulated proteins include succinate dehydrogenase iron-sulfur subunit, flavoprotein subunit, cytochrome b-556 subunit, and a hypothetical membrane protein similar to charperone DnaJ. Some of these changes were further verified by enzyme activity assay.

盐胁迫诱导上调表达的蛋白包括ABC型转运蛋白，3-磷酸甘油透性酶，嘧啶核苷转运蛋白和甲酸脱氢酶；下调表达的蛋白包括琥珀酸脱氢酶铁硫亚基、黄素蛋白亚基、细胞色素b556亚基，以及分子伴侣DnaJ的同源蛋白，酶活力测定结果表明胁迫条件下上述蛋白的活性变化与表达量变化相一致。

2 STR-PCR We analysed the results of STR with the silver dye in the beginning. The silver dye of STR analysis on a sporadic DMD family shows the band confirmation is subjective by eyeballing. It can not detect the small repeats and the size of polymorphic fragments. For limitation of the silver dye, we analysed the band size of STR with the SAGAGT Genotyping System. Primer are designed according to the nucleotide sequence of five STR markers (located in 5' terminus and intron 44, 45, 49, 50) of dystrophin gene. The 5' end of the forward primer are attached a M13 tailed primer which conjugated to the infrared flourescent dye.

根据dystrophin基因5个多态位点（44、45、49和50号内含子以及5'端启动子区的序列）设计引物，在这些STR的上游引物5'端加一可被红外线荧光物质IRDye700识别标记的M13fw的尾：CAC GACGTT GTA AAA CGA C 通过PCR扩增出重复序列本身，经高分辨率的变性聚丙烯酰胺凝胶电泳后，利用红外激光遗传分析系统及SAGA〓基因分型软件对凝胶上的扩增产物及内标的位置，进行扫描分析，确定产物片段的大小。

Mutation rate at exon of GH in five bovine species was very low with the percentage of 3.48%. The majority of nucleotide substitution was nonsense mutation and only one missense mutation was observed. Molecule tree based on haplotypes of bGH at exon 5 showed that differentiation was apparent relatively between Bubalus bubalis and Bos taurus, Bos indicus, Bos grunniens, Bos frontalis. There was no apparent differentiation among other four bovine species and they shared mutual ancestral sequence.

序列分析表明，5个牛种GH基因外显子5的遗传变异水平较低，平均核苷酸变异率约为3.48%，而且绝大多数位点的核苷酸替换是同义突变，仅发现1个错义突变位点；从GH基因外显子5序列单倍型构建的分子进化树来看，水牛与普通牛、瘤牛、牦牛及大额牛的分化相对比较明显，其他4个牛种之间并无明显分化，还享有共同的祖先序列。

Ribonucleic acid and 5'-nucleotide were tested for fructification of Tricholoma matsutake in the field.

摘 要：施用核糖核酸和5'-核苷酸试验，其对生长于林间的松茸子实体的活化作用。

This result showed that the nucleotide sequence of the coding region and accordingly amino acid sequences of Myf-5 gene of gayal and cow, chimpanzee, rhesus monkey, human, dog, house mouse, Chinese softshell, chicken and zebrafish were quite conservative.

大额牛与普通牛、黑猩猩、恒河猴、人、狗、家鼠、软体贝壳、鸡、斑马鱼的Myf-5基因编码区核苷酸序列同源性分别为99.0％、90.0％、90.5％、90.5％、87.2％、84.8％、72.9％、64.3％、51.8％，相应的氨基酸序列同源性分别为99.6％、94.9％、94.6％、94.9％、89.9％、88.7％、81.6％、70.4％、56.6％，这说明大额牛与其他9个物种在Myf-5基因的编码区核苷酸和相应氨基酸序列上具有较高的保守性。
