Switching of DNA: We address the conformational heterogeneity of DNA on the secondary structure level. While it has been demonstrated that RNA is able to modulate function by changing its folding state, we show for the first time that DNA too can undergo transitions between energetically similar folding states on a time scale that is relevant for biological processes (see figure).
DNA 的转换:我们在二级结构水平上解决 DNA 的构象异质性。虽然已经证明 RNA 能够通过改变其折叠状态来调节功能,但我们首次表明 DNA 也可以在与生物过程相关的时间尺度上经历能量相似的折叠状态之间的转换(见图)。
