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, radiation, or heat.

This glossary of biology terms is a list of definitions of fundamental terms and concepts used in biology, the study of life and of living organisms.It is intended as introductory material for novices; for more specific and technical definitions from sub-disciplines and related fields, see Glossary of cell biology, Glossary of genetics, Glossary of evolutionary biology, Glossary of ecology ...
A specially denatured alcohol (SDA) is one of many types of denatured alcohol specified under the United States Title 27 of the Code of Federal Regulations Section 21.151. [11] A specially denatured alcohol is a combination of ethanol and another chemical substance, e.g., ethyl acetate in SDA 29, 35, and 35A , added to render the mixture ...
Lysis (/ ˈ l aɪ s ɪ s / LY-sis; from Greek λῠ́σῐς lýsis 'loosening') is the breaking down of the membrane of a cell, often by viral, enzymic, or osmotic (that is, "lytic" / ˈ l ɪ t ɪ k / LIT-ik) mechanisms that compromise its integrity.
The technical definition of a nucleosome includes a segment of DNA about 146 base pairs in length which makes 1.67 left-handed turns as it coils around the histone core, as well as a stretch of linker DNA (generally 38–80 bp) connecting it to an adjacent core particle, though the term is often used to refer to the core particle alone.
A former SpaceX engineer allegedly killed his world traveler wife of five months and critically injured his mom during a horrific attack in a small Maine town. Samuel Whittemore, 34, was visiting ...
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. The opposite, a decrease of absorbance is called hypochromicity.
After calling USAID "corrupt," President Donald Trump has moved to place all global workers for the federal aid agency on leave. Winter is continuing to rear its ugly head this week across the ...
