In this communication, we demonstrate for the first time the proof of concept that single-walled carbon nanohorns can be used as an effective fluorescent sensing platform for nucleic acid detection with a high selectivity down to single-base mismatch.

Nuclease activity was dissociated from proteolytic activity when Sachs confirmed the observations of Milroy that an agent which attacked nucleic acid to liberate inorganic phosphoric acid could not liquefy gelatin and that proteolytic enzymes liquefied gelatin but could not attack nucleic acid (1). Henceforth the rate of separation of inorganic phosphoric acid from nucleic acid became the exclu...

Submitted for the MAR06 Meeting of The American Physical Society A Density Functional Theory Study of the Non-local Correlations between Nucleic Acid Base Pairs VALENTINO R. COOPER, TIMO THONHAUSER, DAVID C. LANGRETH, Rutgers University — The interactions of nucleic acid bases are fundamentally important in determining the behavior and structure of biologically important molecules such as DNA a...

We present NAFlex, a new web tool to study the flexibility of nucleic acids, either isolated or bound to other molecules. The server allows the user to incorporate structures from protein data banks, completing gaps and removing structural inconsistencies. It is also possible to define canonical (average or sequence-adapted) nucleic acid structures using a variety of predefined internal librari...

In this communication, we demonstrate for the first time that conducting polymer polyaniline (PANI) nanofibres can serve as a novel fluorescent sensing platform for nucleic acid detection with a high selectivity down to single-base mismatch.

Double helix variations of glycol nucleic acids (GNA) are revealed by the atomic resolution crystal structure of a 6mer GNA duplex containing solely Watson-Crick type hydrogen-bonded base pairs.

infectious bronchitis (ib) disease is one of the important respiratory diseases of poultry that causes annually large economic losses in poultry industry of iran. the aim of this study is molecular characterization of s1 gene of iranian infectious bronchitis viruse (ibv) belonged to 793/b serotype. the whole s1 gene of three local ibv strains in rt-pcr, showed a band above 1600 base pair (bp) i...
