赛斯纳飞机公司 - 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 。 - To isolate hfl - , hf2 gene encoding flavonoid - 3 ' , 5 ' - hydroxylase ( f3 ' , 5 ' h ) from petunia hybrida of the purple flower , we used a polymerase chain reaction ( pcr ) amplification using the genomic dna as a template . the result indicated that the hfl dna was 2797bp in total length and encoded 506 amino - acid , containing three extron and two intron ; hf2 dna was 2223bp in total length and encoded 509 amino - acid , containing three extron and two intron . comparison of the sequence with genbank databases revealed that hfl dna and hf2 dna shared significant nucleotides identity ( 98 . 97 % and 99 . 04 % respectively ) and amino - acid identity ( 99 . 41 % and 99 . 41 % respectively )
Hf1dna全长2797bp ，包括3个外显子， 2个内含子，其中一个开放阅读框架( orf )编码506个氨基酸，与文献报道的序列相比较，具有98 . 97核苷酸同源性与99 . 41氨基酸同源性： hf2dna全长2223bp ，包括3个外显子， 2个内含子，其中一个开放阅读框架( orf )编码509个氨基酸，与文献报道的核苷酸同源率为99 . 04以及氨基酸同源率为99 . 41 。 - The clones inserted with ban fragments of b . napus and a . thaliana were sequenced and compared with the sequences in genbank . the results showed that the ban fragment of a . tha liana had the same sequence ( 779bp ) as reported . the ban fragment of b . napus was 780bp and its extron had 90 % of homology with those of a . thaliana ban ( 90 % )
Pcr产物经克隆测序和比较分析显示，拟南芥ban片段( 779bp )与已报道的完全相同，甘蓝型油菜ban片段( 780bp )与拟南芥ban外显子的同源性为90 ，但内含子的同源性仅为74 。
