查询词典 transversion

The results of genetic analysis, such as GC content, transition/transversion rate ratios, synonymous substitution rates, indicated that the br fragments with high level of genetic divergence are faced with both purifying selection and bias mutation pressure.

随后的遗传分析，包括GC含量、转换与颠换的比率、同义突变率分析，表明br基因间具有较高的遗传分歧程度，并面临着净化选择和偏倚突变压的双重抑制。

The substitution of a purine for a pyrimidine, or vice versa is a transversion

嘌呤为嘧啶取代或嘧啶为嘌呤所取代，叫做颠换。收藏反馈

By using Genedoc to compare the sequences of the 45 samples, no base deletion and insertion were observed and 45 variation sites were found which include 43 transition sites and 2 transversion sites.

用Genedoc软件进行序列比较，在这45个个体中未发现碱基插入或缺失，共检测到45个变异位点，其中有43个转换位点和2个颠换位点。

Together with the cited sequences of other species (cattle, zebu cattle and buffalo), the molecular phylogenetic tree was therefore built to probe phylogenetic relationship between Bovine subfamilies, Total 5 variation sites were examined and two types of mutation, transition and transversion, were observed, with the overage percentage of nucleotide variation of 1.66%. It demonstrated the poverty of polymorphism at exon 5 of GH gene of three bovine species. There was only one missense mutation out of 5 mutation sites which led to the shift between leu and val amino.

结果表明，在雷琼牛、巴州牦牛和巴州蒙古牛中共检测到5个变异位点，核苷酸取代方式仅有转换和颠换，核苷酸平均突变率仅为1.66%，说明这3个牛种GH基因外显子5多态性较为贫乏；5个变异位点中仅有1个为错义突变，导致亮氨酸和缬氨酸的转换，但该突变在牛种中分布有差异。
