4. engineering dhqase ( arod ) - deficient e. coli mutant with a second copy of the arob gene gene targeting technique was used to disrupt the arod gene in e. coli chromosome. the mutant 31bk was engineered, in which homologous recombination of the arobkanr gene cassette into the arod locus ( arod : : arobkanr ) of the e. coli strain atcc31884 genome utilized the helper plasmid pkd46 with red system. the host cell 31bk lacked catalytic activity of dhqase ( arod ) and had a second copy of the arob gene, so it improved carbon flow into the quinic acid biosynthesis direction
構建宿主菌基因精確定位突變株31bk （ arod : : arobkan ~ r ）為了改變代謝途徑脫氫奎尼酸（ dhq ）分支點上的代謝流量，使之充分流向目的產物奎尼酸合成方向，利用基因打靶技術構建了31884宿主菌arod基因精確定位插入突變體，使dhq脫水酶（ dhqase ）失活，阻斷了碳代謝流流向芳香氨基酸生成的方向，同時用同源重組的方法將arob基因定位整合入染色體上，解除了限速酶對碳代謝流通過共同途徑到達dhq的阻遏影響，並減輕代謝負擔。 -
Recovery of microtubule organizing centers in enucleated oocytes and condensation of chromosome and organization of spindle in reconstructed embryos were analysed. a non - invasive method of enucleation mouse oocytes has been developed. firstly, the progression of mouse oocytes in meitosis i was ascertained by immunofluoresence technique
另外，本試驗通過在m16基礎上添加eaa 、 non - eaa和葡萄糖顯著提高了胚胎的桑椹率、囊胚率和孵化率；單獨添加葡萄糖的培養液，其桑椹率顯著升高，但囊胚率和孵化率的升高並不顯著，所以胚胎培養液中氨基酸和葡萄糖能協同促進胚胎發育。 -
