G-Quadruplexes

In the past few decades a large number of scientific papers, both computational and experimental in vitro and in vivo, have demonstrated that G-rich DNA sequences can fold as intrastrand quadruple helix structures called G-quadruplexes or G4-DNA. G4-DNA is stabilized by G-quartets, planar arrays of four guanines paired by Hoogsteen hydrogen bonding, and monovalent alkali cation, K+ or Na+, located in the central cavity of the structure. In the human genome the sites that can potentially form G4- DNA are estimated to be more than 3,00,000. They are not randomly distributed, but located preferentially in repetitive genomic sequences such as the telomeres, ribosomal DNA and the immunoglobulin heavy-chain switch regions. OMICS group publishes articles involving many subjects like Pharmacy, Life sciences, Engineering, Medical, Management and Clinical. Each of the above mentioned department publishes all the major kinds of articles which include; research, review, mini-review, short communication, case report etc.
