Descriptor cuádruplex G
Entry term(s) G-cuádruplex
cuádruples G
Scope note: Estructuras de ADN y ARN de orden superior constituidas por secuencias ricas en guanina. Se forman alrededor de un núcleo de al menos dos tétradas apiladas de bases guanínicas (GUANINA) unidas por puentes de hidrógeno. Pueden formarse a partir de una, dos o cuatro hebras independientes de ADN (o ARN) y pueden adoptar una gran variedad de configuraciones según la dirección, la longitud y la secuencia de las hebras.

Scope note: Higher-order DNA and RNA structures formed from guanine-rich sequences. They are formed around a core of at least 2 stacked tetrads of hydrogen-bonded GUANINE bases. They can be formed from one two or four separate strands of DNA (or RNA) and can display a wide variety of topologies, which are a consequence of various combinations of strand direction, length, and sequence.
