G-quadruplexes are non canonical secondary structures held together by Hoogsteen bonded planar guanine quartets formed in G-rich sequences in DNA and RNA. Considerable research over the past three decades has contributed to a great deal of understanding of these unusual structures in DNA. Various factors governing the stability of DNA quadruplexes coupled with their in vivo existence have been well documented. RNA has emerged as a key regulatory player in the functioning of the cell shifting the ...
