Networking. Organizations have a networking relationship when they exchange information in order to help each organization do a better job. For example, if a school and a community counseling center share information about their counseling services for youth, that is a form of networking.
Phenolâchloroform extraction is a liquid-liquid extraction technique in biochemistry and molecular biology for purifying nucleic acids and eliminating proteins. In brief, aqueous samples are mixed with equal volumes of a phenol: chloroform mixture.After mixing, the mixture is centrifuged and two distinct phases are formed, because the phenol: chloroform mixture is immiscible with water.n brief, aqueous samples are mixed with equal volumes of a phenol: chloroform mixture.

When added to a solution for this sort of chemical testing, phenolphthalein is colorless. Phenolphthalein will not generally dissolve in water but it can be dissolved by alcohols such as ethanol and ether. The solutions that contain phenolphthalein for chemical testing are therefore usually alcohol based.hen added to a solution for this sort of chemical testing, phenolphthalein is colorless.
