The stability of these triple helixes is so high that homopyrimidine PNA targeted to purine tracts of dsDNA invades the duplex by displacing one of the DNA strands. 这种三螺旋体的稳定性极高,以至于在同型嘧啶PNA靶向双链DNA嘌呤道时,能取代其中一条DNA链侵入双螺旋。
These twelve helixes certainly do not comprise all of the information inside the light-encoded filaments. 当然这些十二个螺旋不组成内在光编码细丝全部信息。
The formation of the twelve helixes will not mean that you will become completely informed as a species. 十二个螺旋的形成将不意味你们将彻底成为有知识的一个族类。
Formed from a series of interlocking helixes it presented significant analytical and construction challenges. 它是由一系列带有重要分析意义和建筑挑战的联锁螺旋状物体组成。
Harvard University molecular geneticist George church has transcribed an entire 304-page book he wrote, regenesis: how synthetic biology will reinvent nature and ourselves, into the four-letter genetic alphabet in spiral helixes. 哈佛大学分子遗传学家乔治丘奇成功地将其共304页的著作《重生:合成生物学将如何彻底改造自然和人类自身》转录成由四个字母组成的遗传字母盘旋上升式螺旋。
However, the forming of the twelve helixes will be plenty to give you, as a species, a much bigger picture of who you are. 然而,作为一个族类,十二螺旋的形成,将极大地赋予你们是谁的更大的图片。
There are many helixes of dihedral angle, and the whole skeleton forms a large helix in the structure of the rotatory isomer. 其结构中包含许多二面角螺旋,而且具有旋光性的异构体,其结构的整体骨架也构成一个大的螺旋。
Among the non-standard base-pairing, the overwhelming majority is GU and it is concentrated in the region of gaps of two continuous double helixes and G is preferred to dominance at 10,27,49 sites. 在非标准配对中以GU为主而且集中在两个连续双螺旋的缺口处,又发现在第10、27、49位G居多现象,其意义有待阐明。

A Study of the Effects of the Helixes on the Mechanical Characteristics of the Vertical Loops 螺圈对垂直曲力学行为的影响
Its cDNA encodes a protein of 276 amino acid residues with a deduced molecular weight of 30 kD, which PI is 8.27. It is hydrophobic protein without transmembrane helixes. 研究结果表明,小盐芥了TZF1cDNA编码蛋白由276个氨基酸组成,推测其分子量为30kD,等电点8.27。
Secondary structurs of the protein were mainly alpha helixes and random coils, and little beta sheet and beta turn. 二级结构预测,显示该蛋白主要以a-螺旋和无规卷曲为主,含少量的β-折叠,间或有B-转角。
