When subjected to denaturing factors like increased heat or chemicals like formamide in low levels, DNA is partially denatured in a predictable pattern based on its nucleotide content in different regions. [1] This allows unique fingerprints or ‘barcodes' to be generated for molecules with different sequences not unlike restriction mapping.
In biochemistry, denaturation is a process in which proteins or nucleic acids lose folded structure present in their native state due to various factors, including application of some external stress or compound, such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), agitation and radiation, or heat.

Hyperchromicity can be used to track the condition of DNA as temperature changes. The transition/melting temperature (T m) is the temperature where the absorbance of UV light is 50% between the maximum and minimum, i.e. where 50% of the DNA is denatured. A ten fold increase of monovalent cation concentration increases the temperature by 16.6 °C.
Ribonuclease (commonly abbreviated RNase) is a type of nuclease that catalyzes the degradation of RNA into smaller components. Ribonucleases can be divided into endoribonucleases and exoribonucleases, and comprise several sub-classes within the EC 2.7 (for the phosphorolytic enzymes) and 3.1 (for the hydrolytic enzymes) classes of enzymes.
