負染色 的英文怎麼說
中文拼音 [fùrǎnshǎi]
負染色
英文
negative staining-
4. engineering dhqase ( arod ) - deficient e. coli mutant with a second copy of the arob gene gene targeting technique was used to disrupt the arod gene in e. coli chromosome. the mutant 31bk was engineered, in which homologous recombination of the arobkanr gene cassette into the arod locus ( arod : : arobkanr ) of the e. coli strain atcc31884 genome utilized the helper plasmid pkd46 with red system. the host cell 31bk lacked catalytic activity of dhqase ( arod ) and had a second copy of the arob gene, so it improved carbon flow into the quinic acid biosynthesis direction
構建宿主菌基因精確定位突變株31bk （ arod : : arobkan ~ r ）為了改變代謝途徑脫氫奎尼酸（ dhq ）分支點上的代謝流量，使之充分流向目的產物奎尼酸合成方向，利用基因打靶技術構建了31884宿主菌arod基因精確定位插入突變體，使dhq脫水酶（ dhqase ）失活，阻斷了碳代謝流流向芳香氨基酸生成的方向，同時用同源重組的方法將arob基因定位整合入染色體上，解除了限速酶對碳代謝流通過共同途徑到達dhq的阻遏影響，並減輕代謝負擔。For example, while seeking the gene responsible for making betaglobin, a key component of the hemoglobin protein that transports oxygen through the bloodstream, scientists identified a dna sequence that looked like a globin gene but could not possibly give rise to a protein
舉例來說，科學家在進行染色體定位，希望找出在血液里負責運送氧氣的血紅素中、一種關鍵組成物球蛋白的基因位置時，卻發現另一段dna ，序列看起來像是球蛋白基因，但顯然不可能製造出蛋白質。That is because only large firms have been able to afford the supercomputers needed to mutate and crossbreed large virtual genomes ? and then simulate the behaviour of their offspring ? for perhaps 20m generations before the perfect design emerges
因為只有那些大公司才能負擔得起費用來使用必須由超級計算機來進行的對大型虛擬染色體進行變異和雜交- -以及隨后對這些染色體後代行為模擬- -在完美的設計浮現之前，可能需要經歷2000萬代。Negative staining technique
負染色法Who should undertake the responsibility for white pollution
誰該為白色污染負責We found that with the time prolongation of ogd, ttc staining of the hippocampal slices was reduced and ldh release rate was increased consistently. the percent decrease of ttc staining was significantly correlated ( r = - 0. 933 ) to the percent increase of ldh release due to ogd insults
結果發現，隨著缺氧缺糖時間的延長腦片hc染色逐漸下降， ldh釋放率也逐漸增高， ttc染色下降百分率和ldh釋放百分率呈顯著負相關（ r 。In this paper, the state - of - the - art on the investigations is summarized and the theoretical system framework of the research contents on green design & green manufacturing is brought forward. and mechanism of pollution emerging in different processes is analysed on the basis of practical processes of production of ck7525 numerical controlled machine tool made in changzhou machine tool general works. applying the theoretical system framework of the research contents on green design & green manufacturing, the slide rail of machine tool is carried on design for disassembly and the lubricate oil way and packing are carried on design for recycling
本文在總結國內外現有研究狀況的基礎上，建立了綠色設計與製造的研究內容理論體系；並依據常州機床總廠ck7525數控機床的實際生產過程，分析在不同加工過程中污染產生的機理；應用綠色設計與製造的理論體系對機床的導軌進行可拆卸設計、潤滑油路和包裝可回收性設計；對綠色鑄造粘結劑、綠色熱處理工藝、干切削刀具選用進行試驗分析；應用泛環境函數和金屬材料環境負荷評價模型對機床的主要材料進行生命周期評價。Trait mapping ? narrowing the probable location of the gene underlying a trait to a particular chromosomal region, or locus ? has shown that many of the changes humans have made in modern cereals map to similar loci in the genomes of related crop plants
性狀定位是找出負責某一性狀的基因在染色體上特定區域的技術，經由這種技術，顯示出人類對現代穀物物種造成的改變，都可回溯到相關植物基因組上類似的基因座。Chromosome disorders, one of the most important genetic diseases, are the most frenquent cause of mental retardation. these disorders are thus important public health problems for no entirely satisfactory prevention measures now exist
染色體不分離所導致的疾病是最主要的遺傳病之一，也是導致智力發育障礙的最主要原因，其發生給社會和家庭帶來極大的負擔，其中以down綜合征（ ds ）最為常見。With the development of pattern recognition, and image processing methods begin widely used in medicine. automatic chromosome analysis becomes possible. the automatic karotyping will increase then efficiency of availability, and relax then medical persons, it can be performed by the operators who have no professional technology and experiences. at then same time then remote chromosome analysis becomes possible
模式識別技術的發展，以及圖像處理技術在醫學中的廣泛應用，使得自動化染色體分析成為可能，利用計算機進行染色體自動分析會大大提高工作效率，也減輕了醫護人員的負擔，並且它不依賴于工作人員的狀況，工作人員也不需要專家級的技術和經驗，同時也為染色體分析遠程醫療提供了可能。分享友人
