- Functional divergence analysis for this family provided statis-tical evidence for shifted evolutionary rate after gene duplication. 功能分化的统计分析表明在基因重复后存在不同的进化速率。
- 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。
- This pseudogene (named makorin1-p1) is a greatly shortened copy of makorin1, an ancient gene that mice share with fruit flies, worms and many other species. makorin1是小鼠、果蝇、蠕虫以及许多其他物种都共有的古老基因。
- 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。

- The fortress was the nucleus of the ancient city. 这城堡是这座古城的中心。
- These chromosomal regions could be composed of the now-defunct remains of ancient genes, known as pseudogenes, which were once functional copies of genes but have since lost their protein-coding ability (and, presumably, their biological function). 这些染色体区域可能由现在死亡的远古基因残余组成,如熟悉的假基因,它们曾经发挥过基因复制功能只是已经丧失了蛋白质编码能力(大概为它们的生物学作用)。
