Extraction of large - fragment genomic dna in order to gain dna template of pcr amplification ( long pcr amplification and salvage pcr amplification ) which was high purity and large fragment, three methods were used to extract genomic dna of bacillus subtilis, i. e. low melting - point agarose embedding method, sds - proteinase k - phenol chloroform extraction method and bacterial genomic dna extraction kit method. the genomic dna of bacillus subtilis were gained by these methods, and the operated programs of the methods were improved. the results showed that the genomic dna extracted by low melting - point agarose embedding method were obviously biggest than that of another two methods
大片段基因組dna的提取為了獲得用於pcr擴增（長距離pcr擴增和分段pcr擴增）的高純度、大片段（至少為pcr產物長度的4倍）的dna模板，應用三種方法：低熔點瓊脂糖包埋法， sds -蛋白酶k -酚氯仿抽提法和細菌基因組dna提取試劑盒法，分別提取獲得了枯草桿菌基因組dna ，並對3種方法的操作程序進行了不同程度的改進，結果表明：低熔點瓊脂糖包埋法提取的基因組dna片段明顯大於后兩種方法，採用0 . 5瓊脂糖凝膠電泳3h ，仍然跑不出加樣孔。 -
The second phase is the analysis to the inner structure of web table. this thesis discusses deeply at this phase. the key point to recognize the table structure is to extract a abstract logistic table from variants of table structures. this thesis presents a table analysis modal, according to which, the physical table, the abstract logic table and
