G-quadruplex conformations within a sequence of three quadruplex units of human telomeric DNA were studied by two-frequency pulsed electron paramagnetic resonance (EPR) spectroscopy. In contrast to some individual G-quadruplexes, within the higher-order human telomeric sequence a (3+1) hybrid structure is formed.
通过两频脉冲电子顺磁共振(EPR)光谱研究了人类端粒DNA的三个四链体单元序列中的G四链体构象。与某些单独的G-四链体相反,在高阶人端粒序列内形成了(3 + 1)杂合结构。
