体外重组 meaning in English

in vitro recombination
recombination in vitro

The research adopts that hu - - ifn gene were introduced into the nuclei of oocytes or cytoplasm of grass carp to develop anti - disease transgenic grass carp breeding researches , combing the adva ntag e of hu - - ifn gene and breeding by genetic engineering , with an aim of finding out an effective way of solving antivirus of hemorrhagic virus of carp completely . in research of transgenic fish , hu - - ifn gene ( recombination gene ) is cutdown and introduced into the nuclei of oocytes or cytoplasm of grass carp at one - cell or two - cell stage via micyoinjection by narashige micyoinjection apparatus
本研究的目的在于以人的-干扰素基因( ifn - )作为目的基因，与鲤鱼-肌动蛋白基因启动子在体外重组，利用原核显微注射转基因技术将人-干扰素基因导入草鱼基因组而开展的抗病转基因草鱼育种研究，其结合了干扰素和基因工程育种抗草鱼出血病病毒的优点，以期获得对草鱼出血病具有天然抗性的转基因鱼，并在此基础上培育出草鱼抗病新品系。
