DNA and RNA sequences rich in guanine can fold into noncanonical structures called G-
quadruplexes (GQs), which exhibit a common stem structure of Hoogsteen hydrogen …

The formation of G-quadruplexes (GQs) occurs in guanine-rich sequences of DNA and RNA,
producing highly stable and structurally diverse noncanonical nucleic acid structures. GQs …

Guanine quadruplex (GQ) is a noncanonical nucleic acid structure formed by guanine-rich
DNA and RNA sequences. Folding of GQs is a complex process, where several aspects …

Abstract G-quadruplexes (G4) are nucleic acid conformations of guanine-rich sequences, in
which guanines are arranged in the square-planar G-tetrads, stacked on one another. G4 …

Telomeric DNA is guanine-rich and can adopt structures such as G-quadruplexes (GQs) and
G-hairpins. Telomeric GQs influence genome stability and telomerase activity, making …

Guanine-rich oligonucleotides can form a unique G-quadruplex (GQ) structure with stacking
units of four guanine bases organized in a plane through Hoogsteen bonding. GQ structures …

G-quadruplexes (GQs) are four-stranded noncanonical DNA and RNA architectures that can
be formed by guanine-rich sequences. The stability of GQs increases with the number of G …

DNA G-quadruplexes in human telomeres and gene promoters are being extensively
studied for their role in controlling the growth of cancer cells. G-quadruplexes have been …

G-quadruplexes (GQs) are key noncanonical DNA and RNA architectures stabilized by
desolvated monovalent cations present in their central channels. We analyze extended …

Telomeric DNA consists of tandem repeats of the sequence d (TTAGGG) that form G-
quadruplex structures made of stacked guanines with monovalent cations bound at a central …
