Was added, the absorption of morin at 350nm decreased and a new absorption peak at 419nm appeared. adding of nucleic acids to the morin - al binary system leads to decrease of the absorption at 350nm and great increase at 419nm. there is an isochromatic point at 370nm. the increase of absorbance at 419nm is proportional to the amount of nucleic acids added within certain concentration range. based on this, a new sensitive nucleic acids analysis method is established. the linear ranges of ct dna, fs dna and y rna are 0. 7135. 4 0. 6425. 6 and 0. 9428. 4g ml, respectively
鋁離子的加入使桑色素350nm處的吸收峰下降，在419nm處出現桑色素-鋁絡合物的吸收峰。再往桑色素-鋁離子二元體系中加入核糖核酸或脫氧核糖核酸，則進一步引起桑色素350nm吸收峰的降低， 419nm處的吸收大大加強，同時在370nm處有一等色點。 419nm處吸光度的增加值與加入的核酸量在一定范圍內成正比，基於此建立了在較寬范圍內測定核酸的方法。 -
By comparing the biological characteristics of original normal filament, linear filament and the curved filament retransited from linear filament, certain evidence of the morphologic variation regulated by a special transposon are detected on the level of protein and dna, which will help us to discover the mechanisms of this morphologic variation on molecular genetics level and solve the problem in production of spirulina in large scale
在比較了正常藻絲體、變直藻絲體及回復正常螺旋形態的藻絲體一組材料生物學特性的基礎上，進一步在蛋白質及dna水平上找到了轉座子調控此形態變異的某些證據，為闡明螺旋藻形態變異與重建的分子遺傳學機制以及解決螺旋藻大規模生產的實際問題提供理論依據。 -
Both the frequency and intensity of 1146. 0cm - 1 change largely, etc. discussed and compared the mechanism of these interaction in detail we got some conclusions as following : both zn2 + and cd2 + ions can chelate with po2 - and come into being - po2 - me2 + n7 ( purine ) chelate. as to zn2 + ions, when r2. 0, the quantity of po2 - zn2 + n7 is directly linear with r. when r2. 0, zn2 + ions even can chelate with c at n3 - o2 sites and this chelation will disrupt the h - bond between gc base pairs and make the dna structure unstable. as to cd2 + ions, only when r is within 1. 0 - 1. 5 can this chelation take place and the relation of the quantity of this chelate with r is not easy to conclude
通過對這些變化進行詳細討論和分析，我們得到了如下的結論： zn ~ （ 2 + ）和cd ~ （ 2 + ）都可以跟dna的磷酸基團螯合，形成- po _ 2 ~ - … me ~ （ 2 + ） … n7 （ g ）螯合物，但是前者的螯合跟離子濃度有很大的關系，在摩爾濃度比小於2 . 0時，螯合物的生成量跟r成正比關系，而後者的螯合跟離子的關系不是很明顯，只有當r處於1 . 0至1 . 5之間時，螯合作用才能進行，並且螯合物的生成量跟r之間沒有很明顯的關系存在。 -
Measurement of the fragment lengths was accomplished with the use of scion image analyzed software, which allows a curved fragment to be measured in a stepwise manner at nanometer level resolution, and the change laws of three forms of dna, supercoil, open circular and linear form as the dose increased were obtained
