Schematic structure of V-shaped G-quadruplexes. (A) Two-layer V-shaped G-quadruplex, adapted with permission from (17). (B) A self-assembled homodimeric leaped V-shape G-quadruplex (PDB: 1U64). (C) An intramolecular leaped V-shape G-quadruplex (PDB: 2KPR). (D) An intermolecular heterodimeric leaped V-shape G-quadruplex formed by two chains of different lengths. The short chain is indicated by the black dotted line, and the V-shaped loops are colored in black. Other loops and G-columns are colored in light gray. Syn and anti guanines are indicated by solid and hollow rectangles, respectively.
