  • In arid climates, surface water is generally better than ground water in headwater areas, but poorer downstream .
    在干旱气候的上游区,地表水一般较地下水好,但下游的地表较差。
  • Genetic variation in 5 ' - upstream region and the second intron of h - fabp gene in nine pig breeds
    上游区和第二内含子的遗传变异
  • Then , 5 . 5kb thrombiotin gene was amplified with the same technique from the genome of a baby ' s blood , which included the begining part of intronl to the teminator . in addition , 6 . 0kb and 1 . 8kb homlogous arms were also amplified from a cow with high yield . the 6 . 0kb homologous arm contains the promotor , extron 1 , extron2 , extron3 and intron 1 , intron2 and part of the intron3 fragment , while the 1 . 8kb homologous right arms contains exon13 , exon14 and part of intron 13 , the whole intron14 and part intron 14 of asl - casein gene of bovine
    通过长片段pcr从高产奶牛的基因组中获得了打靶所需的长、短同源臂序列,长度分别为6 . 0kb和1 . 8kb ,位于s1 -酪蛋白基因的5上游区到第三内含子和十二到十四内含子;从绵羊全血基因组克隆得到了绵羊的-酪蛋白基因启动子区到第二内含子区4 . 1kb的5调控序列;利用同对引物克隆得到了水牛的同基因序列;从广西当地一婴儿脐血基因组中通过获得了人血小板生成素基因,位于第1内含子到终止子后部分的序列,长达5 . 5kb 。
  • Then the cryld - lacz was introduced into different hosts . analysis of activity of p - galactosidase showed that the cryld and crylab expressed differently in different hosts . comparison of expression of cryld with crylab in the same host revealed that different upstream and competition for < j - factor were involved in the difference of cryld and crylab expression
    结果表明,在不同遗传背景的菌株中, cry1d - lacz和cry1ab - lacz融合基因的表达完全不同,表明同一基因在不同菌株中转录调控不同,也许一些宿主专一性的因子参与了转录调控;而在同一菌株中cry1d - lacz和cry1ab - lacz的表达差异是由于上游区的不同以及竞争有限的因子所致。
  • Through the all - sided tectonic analyses , it can be deduced that there are two aspects will be the hidden defects to the dam and the engineering stability of the reservoir area . one is the dislocation interfaces resulting from the the majiaheba faultage ' s thrusting overriding and other causes of formation . the second is the region of strong deformation , such as the above of the dam , middle and high positions of the lava layers and the regions of overprint of the structure of ne to the one of nw , which should be taken into account especially
    通过区域和坝区错动带的全面构造解析,认为由马家河坝断层逆冲推覆作用而在坝区形成的向金沙江下游缓倾的错动带以及其它成因的错动带是坝区和库区工程稳定的隐患,尤其是变形较强的坝址区上游区、中高层位以及北西向构造期的错动带叠加于北东向构造期错动带的部位,更应该引起足够的重视。
