Dna thermal denaturation graph

WebThermal denaturation is a common technique in the biophysical study of nucleic acids. These experiments are typically performed by monitoring the increase in absorbance (hyperchromism) of a sample at 260nm with temperature (Mergny & Lacroix, 2003; Puglisi & Tinoco, 1989). This wavelength is … WebJun 15, 2014 · The solvent effect on the denaturation of DNA has been recently investigated in the literature. The model Hamiltonian that incorporates a solvent interaction term (Eq. (6)) enhances the base pair dissociation energy and stabilizes the hydrogen bonds between complementary strands.

Hybridization is the process of establishing a non-covalent, sequence-specific interaction between two or more complementary strands of nucleic acids into a single complex, which in the case of two strands is referred to as a duplex. Oligonucleotides, DNA, or RNA will bind to their complement under normal conditions, so two perfectly complementary strands will bind to each other readily.
