DNA and RNA Structure
... Each strand of DNA has directionality. In other words, one edge is not identical to the other and there is no symmetry along the strand. The molecule has two different edges, termed the 3-prime edge and the 5-prime edge. The DNA molecule is arranged such that the two strands are lying next to each o ...
