碱基替换 meaning in Chinese
base substitution
Examples
- To discriminate between drier and passenger mutations , the authors annotated the 921 single - base substitutions that they identified as being either non - synonymous ( changing an amino acid ) or synonymous ( haing no effect on the protein sequence )
为了找出驱动和旅客突变间的差别，研究人员将921种单碱基替换突变分成两类：非同义（改变一个氨基酸）或同义（对氨基酸序列没有影响） 。 - To discriminate between driver and passenger mutations , the authors annotated the 921 single - base substitutions that they identified as being either non - synonymous ( changing an amino acid ) or synonymous ( having no effect on the protein sequence )
为了找出驱动和旅客突变间的差别，研究人员将921种单碱基替换突变分成两类：非同义（改变一个氨基酸）或同义（对氨基酸序列没有影响） 。 - Analysis of the variation of bases of epsps of brassicaceae , solanaceae and poaceae indicate that the evolutionary rates of epsps are different between brassicaceae and solanacea e and the rate in solanaceae is higher than the rate in brassicaceae according to the total substitution rate of bases
分别对十字花科、茄科、禾本科序列的碱基变异情况分析，结果表明， epsps基因在十字花科和茄科中的进化速率不一样，对于总的碱基替换率，茄科高于十字花科。 - Sequence variation analysis exhibits high transition to transversion substitution ratios , and transitions and transversions are unsaturated in the sequence of cytochorme b gene . the base composition of the cytochrome b sequences was highly biased . using a structural model of the cytochrome b protein as a template , we divided cyt b sequence data for species within anserifomes into three functional domains
3 ）序列具有较高的转换颠换比，基因序列中的转换与颠换都未饱和，序列中的碱基组成高度偏倚： 4 ）按照细胞色素为蛋白结构模型，细胞色素b基因全序列可分为三个功能区，碱基替换饱和状况与不同功能区相关联。 - However , the cloned promoter had 18 substitution at 18 sites , 22 deletions at 18 sites and 3 insertion at 3 sites between sites 0 - - - 1273 bp which was reported to control temporal - spatial specific expression , and 3 substitution at 3 sites , 6 deletions at 6 sites between - 1095 bp and - 1273 bp , the key functional sequence area , in comparing with known osg6b
但是与报道的osg6b比较，在决定时空特异性的0 - 1273bp功能区域内，有18处出现18碱基替换， 18处出现22碱基缺失， 3处出现3碱基插入；在核心功能序列区域( - 1095bp - 1273bp )内，有3处出现3碱基替换， 6处出现6碱基缺失。
