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.

2 the organic phase and reduces the formation of insoluble RNA-protein complexes at the interphase (24). Moreover, phenol retains about 10-15% of the aqueous phase, which results in a similar loss of RNA; chloroform prevents this retention of water and thus improves RNA yield (22).uanidinium salts are used to reduce the effect of nucleases. Purified phenol has a density 3of 1.07 g/cm and therefore forms the lower phase when mixed with water (1.00 g/cm 3 FIGURE 1. The procedure of phenolâCHCl 3 extraction.
