  1. 3. the effect of sporulation - independent promotor on toxicity of natural strain in order to study the effect of sporulation - independent promotor ( p3a ), p3a was spliced with the cry1c gene, then inserted into the shuttle vector pht304, and then recombinated plasmid pbmb827 was obtained. after transferring pbmb827 into strain ybt - 1520, it was surprising that the transformants had almost no potency against all lepidopteran larvae tested

    3非依賴芽胞形成icp的cry3a啟動子（ p _ （ 3a ） ）對野生菌株特性的影響帶p _ （ 3a ）和cry1c基因的重組質粒pbmb827轉入ybt - 1520 ，轉化子對所測昆蟲的毒力下降非常明顯，芽胞和晶體也很難脫落。
  2. The hwtx - i gene was chemically synthesized according to its known cdna sequence, the gene was inserted into vector ppic9k which contained aoxj promotor and the sequence of a secreting signal peptide - a - factor, the cloning ppic9k / hwtx - i was constructed and confirmed by two - step pcr and dna sequence analysis, then it was transformed into host strain gs115, a his + muts cell line was screened and multicopy transformants were screened by various g418 concentrations, the multicopy transformant was named gh1. gh1 was cultivated in flasks. after 6 days of induction by 0. 5 % methanol, the supernatant was checked by 16. 5 % tricine - sds page, which showed there was a band in the position of 3. 5 - 6. 1kd, then it was isolated and desalted by ultrofiltration followed by ion exchange of cm column, after reverse phase hplc of ci8 and vacuum drying, the purified rhwtx - 1 was obtained which was proved to be correct recombinant hwtx - i by tricine sds - page, maldi - tof mass spectrometry, amino acid composition analysis, the n - terminal amino acid sequence and its biological activity, the final field of the purified rhwtx - i was about 80mg / l, accounting for 23. 6 % of it total secretory proteins

    將帶有hwtx -基因的ppic9k經blgii線性化后，轉化酵母宿主菌gs115原生質體后經篩選陽性克隆並經表型鑒定為his ~ + mut ~ s酵母菌，進一步用遺傳毒素g418篩選多拷貝的轉化菌株，命名為gh1 ；將gh1甲醇酵母菌用0 . 5的甲醇誘導表達，發酵上清經90飽和度的（ nh _ 4 ） _ 2so _ 4沉澱， yw - 3 （ mwc03000 ）的超濾膜超濾，再經cm陽離子交換， c _ （ 18 ）反相hplc純化得到分子量為4kd左右的組分，其中4289 . 05的組分經質譜鑒定，氨基酸組成分析和序列測定為正確的表達產物，生物學活性表明其活性為天然毒素活性70 % ，表達量為80mg / l 。
  3. As rna polymerase ii leaves a gene promotor to transcribe the coding region, it faces many obstacles, including nucleosomes

    當rnap離開基因的啟動子轉錄編碼區時，遇到包括核小體在內的多種障礙。
  4. 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 。
  5. The gene targeting vector was planning to be constructed by using thrombopoietin gene ( tpo ) gene as purpose gene, as 1 - casein gene as targeting gene, the 5 " sequence of - casein gene as promotor

    以綿羊-酪蛋白基因的5調控區為啟動子，人血小板生成素基因為目的基因，奶牛s1 -酪蛋白基因為靶向基因。
  6. Regulator gene a gene whose product can promotor or prevent the transcription of structural genes, which may or may not be adjacent to other regulator genes, and may even be on another chromosome

    調節基因：這種基因的產物可以促進或抑制結構基因的轉錄，其可能與其他的調節基因相連，也可以不相連，甚至兩者可以不在同一染色體上。
