Abstract
X-ray fiber diffraction studies of duplexes formed by 2-substituted poly(A) and poly(U) provide evidence for the existence of a double helical structure of poly(A).poly(U) held together by Hoogsteen-type base pairing with parallel chain polarity.
摘要
对由2-取代聚腺苷酸和聚尿苷酸形成的双链体进行的X射线纤维衍射研究，为聚腺苷酸·聚尿苷酸通过具有平行链极性的霍格施泰因型碱基配对维系在一起的双螺旋结构的存在提供了证据。
