Physical and chemical properties of DNA

DNA molecules are polymers, DNA solution for the polymer solution, with very high viscosity. DNA absorption of UV radiation, when the nucleic acid degeneration, the increased absorption value; when the degeneration of nucleic acid can be complex, the value of the absorption will revert to the original level. Temperature, organic solvents, pH, urea, and so on-reagent can be caused by degeneration of DNA molecules, DNA, even if a double bond between the hydrogen bond breaking, double helix to solve.
DNA (deoxyribonucleic acid) refers to the DNA (genes and chromosomes an integral part of) the DNA polymer, is the main component of chromosomes. The vast majority of genetic information stored in DNA molecules.
