The G-quadruplex is one of the most frequently studied secondary DNA structures and consists of 4 guanine residues that interact through Watson-Crick and Hoogsteen pairing. The G-quadruplex formation is thought to be a molecular switch for gene expression. Genome-wide analyses of G-quadruplexes have
