Dna base stacking
WebBase stacking and Watson–Crick pairing create stacks of continuous and noncontinuous helices, which define that RNA secondary structure. However, non-Watson–Crick pairing and stacking patterns in helical junctions and internal loops preform a 3D architecture that dictates the angles of emerging helices (compare the angles of H7 and H34 in Fig. 1 ) ( …
