The stability of DNA duplexes is dependent on a complex array of hydrogen bonding among amino and carbonyl groups of the heteroaromatic bases and surrounding water molecules, as well as base stacking interactions. Duplex stability can be significantly increased by adding a further hydrogen bond to a base pair, for ...

Webcomplementary DNA is valid under molecular crowding condition of 40% polyethylene glycol with an average molecular weight of 200 (PEG 200) in 100 mM NaCl. Here, we determined nearest-neighbor parameters for DNA duplex formation under the same crowding condition to predict the thermodynamics of DNA du-plexes in the intracellular environment. WebDNA denaturation, also called DNA melting, is the process by which double-stranded deoxyribonucleic acid unwinds and separates into single-stranded strands through the …
