  • gene : n. 【生物學】基因。 dominant gene顯性基因。
  • duplication : n. 1. 加倍，二重，重復。2. 重疊，雙折。3. 復制，列印；復製品。4. 【生物學】（由染色體迷亂造成的）部分遺傳物質的復制，兩岐。
  1. 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

    摘要基因重復是基因通過不等交換、逆轉錄轉座或全基因組重復等途徑產生一個與原基因相似的基因或堿基序列。
  2. The knowledge to the moral and ethical problems of the duplication of human beings in gene project technology

    對基因工程技術中克隆人的道德倫理問題認識
  3. In this review, we summarized the studies of the molecular mechanisms of gene duplication, the preservation of duplicated gene, the selections acting on duplicated gene, the alternative ways of divergence and the evolution rate

    文章綜述了重復基因的產生機制、保留機制、選擇作用、分化途徑以及重復基因進化速率等方面的相關研究，揭示了基因重復對生物進化的重要性，以引起大家對該領域的關注。
  4. Increasing researches suggest that the whole genome duplication probably have occurred during the process of vertebrates evolution, gene and / or genome duplication be probably the reason of the complexity of vertebrate body structure

    更多的研究表明，脊椎動物在進化過程中很可能發生過整體基因組的復制，基因和廠或基因組的復制可能是引起脊椎動物形體結構復雜性增加的根本原因。
  5. 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

    採用新的數據和方法研究擬南芥基因組的基因倍增過程，通過分析串聯基因倍增和大規模基因倍增的存在比例和同義置換率分佈，並估計大規模倍增后基因流失的比例，揭示了擬南芥基因組一次非常明顯的全基因組倍增，採用科學的方法佑計這次倍增發生在約8000萬年前。
  6. 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帶的數目與基因的多少相關，許多哺乳動物的基因已精確地進行了染色體定位，大量報道證明它們一般分佈在r帶上，而不是g帶上，文昌魚r帶的數目恰恰與脊椎動物起源時發生了兩次基因倍增的假設相吻合。
  7. 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組中含有基因的dna片段復制出一個或更多拷貝的過程，是進化出新物種的主要原因。
