1. The pcr products of gyra of a resistant strain ( sll - 3 ) was sequenced and analysed . when compared to the corresponding sequence of the gyra of salmonella typhimurium from the nucleotide sequences data of the gyra reported by griggs , 5 mutants sites were found in the qrdr . dma sequencing identified in the strain sll - 3 ser to phe change at codon 83 of gyra gene
   對所試菌株染色體的pcr產(chǎn)物行hinfi酶切后電泳檢測表明， cip高敏菌株( 6株)得到預(yù)期大小為363bp 、 206bp 、 99bp的3個條帶；而耐藥菌株和中敏菌株( 10株)電泳檢測到大小為363bp和305bp的2個條帶。
2. The results showed that the open reading frame of chil - 15 cdna encompassed 564 base pairs ( bp ) and encoded a protein of 187 amino acids with three potential n - linked glycosylation sites , four conserved cysteine residues , two out - of - frame atg initiation codons in the 5 " untranslated region , and a signal peptide consisting of 66 amino acids . when it was compared with the published sequence of chil - 15 cdna , 7 mutant sites were found , and 5 amino acids were changed in predicted amino acids , which indicated that chil - 15 may be polymorphic
   結(jié)果顯示，本研究所用白來航雞il - 15cdna5 ’非編碼區(qū)有兩個框外atg起始密碼子，開放閱讀框由564bp組成，編碼187個氨基酸，其中n末端信號肽含有66個氨基酸殘基，在第48 、 149和166位的天冬酰胺殘基上有三個潛在的n -糖基化位點。
3. The mature region cdna of melittin of apis cerana was cloned by using puct - vector developed from pucis vector . the sequence was compared with the corresponding region of melittin of apis mellifera reported in genbank , the mutant site was found in 33rd base ( a : apis mellifera ; g : apis cerana ) , but the primary structure of the two proteins were identical , which suggested melittin , as an important defensive gene , was very conservative in evolution
   測序結(jié)果顯示與意蜂( apismellifera ) melittin成熟區(qū)序列相比，中蜂( apiscerana ) melittin成熟區(qū)序列在第33位存在差異(意蜂為a ，中蜂為g ) ，但兩者蛋白質(zhì)一級結(jié)構(gòu)相同，說明melittin作為蜜蜂一種重要的防御基因在進(jìn)化上保守。
4. It's difficult to find mutant site in a sentence. 用mutant site造句挺難的
