A simple geometric approach is described which suggests that the smaller helical repeat of the homopolymer poly(dA) . poly(dT) relative to DNA (10.1 against 10.6 base pairs/turn) quantitatively reflects the property of the dA . dT base pair to behave like a wedge, of angle 11 degrees, pointing towards dA.
本文描述了一种简单的几何学方法,该方法表明,同聚物聚(dA)·聚(dT)相对于DNA的螺旋重复序列更短(分别为10.1和10.6个碱基对/圈),定量反映了dA·dT碱基对的特性,即其如同一个角度为11度、指向dA的楔子。
