Mutually exclusive formation of G-quadruplex and i-motif is a general phenomenon governed by steric hindrance in duplex DNA
G-Quadruplex and i-motif are tetraplex structures that may form in opposite strands at the
same location of a duplex DNA. Recent discoveries have indicated that the two tetraplex …
