  1. 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

    通過長片段pcr從高產奶牛的基因組中獲得了打靶所需的長、短同源臂序列，長度分別為6 . 0kb和1 . 8kb ，位於s1 -酪蛋白基因的5上游區到第三內含子和十二到十四內含子；從綿羊全血基因組克隆得到了綿羊的-酪蛋白基因啟動子區到第二內含子區4 . 1kb的5調控序列；利用同對引物克隆得到了水牛的同基因序列；從廣西當地一嬰兒臍血基因組中通過獲得了人血小板生成素基因，位於第1內含子到終止子後部分的序列，長達5 . 5kb 。

  3. 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全長2797bp ，包括3個外顯子， 2個內含子，其中一個開放閱讀框架（ orf ）編碼506個氨基酸，與文獻報道的序列相比較，具有98 . 97核苷酸同源性與99 . 41氨基酸同源性： hf2dna全長2223bp ，包括3個外顯子， 2個內含子，其中一個開放閱讀框架（ orf ）編碼509個氨基酸，與文獻報道的核苷酸同源率為99 . 04以及氨基酸同源率為99 . 41 。
  4. 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產物經克隆測序和比較分析顯示，擬南芥ban片段（ 779bp ）與已報道的完全相同，甘藍型油菜ban片段（ 780bp ）與擬南芥ban外顯子的同源性為90 ，但內含子的同源性僅為74 。
