gene duplication meaning in English
基因复制
基因再复制
基因重复
Examples
- Gene duplication is defined as segment of dna duplicate one or more copies , it is believed to be a major mechanism for the generation of evolutionary novelty
摘要基因倍增指基因组中含有基因的dna片段复制出一个或更多拷贝的过程，是进化出新物种的主要原因。 - Gene duplication is one of the most important factors that influence the evolution of genome size , the origination of novel gene , the genetic robustness against null mutations , the speciation , etc
摘要基因重复是基因通过不等交换、逆转录转座或全基因组重复等途径产生一个与原基因相似的基因或碱基序列。 - As the number of r - bands is associated with that of genes , and most genes that have been mapped to mammalian chromosomes with sufficient precision are usually distributed in r - bands rather than in g - bands . this is apparently in agreement with the hypothesis of two rounds of extensive gene duplication leading to the origin of the vertebrates
R带的数目与基因的多少相关，许多哺乳动物的基因已精确地进行了染色体定位，大量报道证明它们一般分布在r带上，而不是g带上，文昌鱼r带的数目恰恰与脊椎动物起源时发生了两次基因倍增的假设相吻合。 - Based on new materials and methods , this paper analyses the tandem and segmental duplication , then estimates the num of the lost gene after gene duplication in the arabidopsis gene family , and we find an evidence for the whole genome duplication in arabidopsis which happened about 80 million years ago
采用新的数据和方法研究拟南芥基因组的基因倍增过程，通过分析串联基因倍增和大规模基因倍增的存在比例和同义置换率分布，并估计大规模倍增后基因流失的比例，揭示了拟南芥基因组一次非常明显的全基因组倍增，采用科学的方法佑计这次倍增发生在约8000万年前。
