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.

Extraction of DNA is often an early step in many diagnostic processes used to detect bacteria and viruses in the environment as well as diagnosing disease and genetic disorders. DNA is the precipitated by mixing with cold ethanol or isopropanol and then centrifuging. 2  The DNA is insoluble in the alcohol and will come out of solution, and the alcohol serves as a wash to remove the salt previously added.
