WebJan 2, 2024 · At a fundamental level, protein denaturation is often defined as any non-covalent change to secondary or tertiary structure of the protein molecule (Equation 8.1b). From this denatured state, the protein can revert to its native state (refold) or interact with other components in the system (aggregate). WebRenaturation. 1. The process of formation of double stranded DNA from single stranded denatured complementary DNA strands. 2. It is effected by cooling. 3. It involves reannealing or formation of hydrogen bonds …

WebHyperchromicity is the increase of absorbance ( optical density) of a material. The most famous example is the hyperchromicity of DNA that occurs when the DNA duplex is denatured. [1] The UV absorption is increased when the two single DNA strands are being separated, either by heat or by addition of denaturant or by increasing the pH level.
