IM general only; coord NIM with DNA or RNA or specific (IM)
Scope Note
Disruption of the secondary structure of nucleic acids by heat, extreme pH or chemical treatment. Double strand DNA is melted by dissociation of the non-covalent hydrogen bonds and hydrophobic interactions. Denatured DNA appears to be a single-stranded flexible structure. The effects of denaturation on RNA are similar though less pronounced and largely reversible.
