The presence and extent of base-paired secondary structure in the protein-free potato spindle tuber viroid RNA has been investigated by spectroscopic techniques. Dye-binding studies with the intercalating dye, ethidium bromide, indicate the presence of base-paired regions in the molecule. Variation of the induced chirality in the dye with the dye to RNA phosphate ratio indicate the presence of two base-paired regions in the molecule.
通过光谱技术研究了无蛋白质的马铃薯纺锤块茎类病毒RNA中碱基配对二级结构的存在情况及范围。用嵌入染料溴化乙锭进行的染料结合研究表明该分子中存在碱基配对区域。染料诱导的手性随染料与RNA磷酸比率的变化表明该分子中存在两个碱基配对区域。
