2.6.A1Crick and Watson’s elucidation of the structure of DNA using model making. DNA分子有两条方向平行(antiparallel)的多核苷酸链组成,中间的碱基依靠氢键联系在一起,形成特殊的双螺旋结构。A与T以两个氢键结合(RNA中是A和U),G与C以三个氢键结合,这种结合方式叫碱基互补配对(co

A protein structural domain that binds DNA and RNA, and that is found most commonly in transcription factors. It consists of a helix–turn–helix structure of 60 amino acids. GAR domain A Gly- and Arg-rich motif that adopts a repeated β-turn structure. It is found most commonly in prote...
Despite wide interest in nucleic acid triple helices, there has beenno stereochemically satisfactory structure of an RNA triple helixin atomic detail. An RNA triplex structure has previously been proposed based on fiber diffraction and molecular modeling [S. Arnott and P. J. Bond (1973) Nature ...
