The QIAgen [kye-uh-jin] spin column is used in procedures to purify this substance such as minipreps.
The QIAgen [kye-uh-jin] spin column is used in procedures to purify this substance such as minipreps. Depending on its environment, this substance can exist in 3 different conformations with differing rises and pitches. This substance displays hyperchromicity when heated and displays an inflection point at its "melting point." Hoechst and DAPI stain this substance by binding to a 12-angstrom groove. The sum of the twist and writhe is this substance's (*) linking number, which can be modified by topoisomerases. This substance's phosphodiester ["phospho"-"die"-"ester"] backbone is not subject to acid hydrolysis, unlike a similar substance whose backbone contains a sugar with one more oxygen. This molecule exists in supercoils wrapped around histones, forming chromatin. For 10 points, name this double helical substance that contains genetic information.
