Notes:
To understand how comparatively simple macromolecular components become biological systems, studies are made of the morphogenesis of bacteriophages. Pulsed field agarose gel electrophoresis (PFGE) has contributed to these studies by: (i) improving the length resolution of both mature, linear, double-stranded bacteriophage DNAs and the concatemers formed both in vivo and in vitro by the end-to-end joining of these mature bacteriophage DNAs, (ii) improving the resolution of circular conformers of bacteriophage DNAs, (iii) improving the resolution of linear single-stranded bacteriophage DNAs, (iv) providing a comparatively simple technique for analyzing protein-DNA complexes, and (v) providing a solid-phase quantitative assay for all forms of bacteriophage DNA; solid-phase assays are both less complex and more efficient than liquid-phase assays such as rate zonal centrifugation. Conversely, studies of bacteriophages have contributed to PFGE the DNA standards used for determining the length of nonbacteriophage DNAs. Among the solid-phase assays based on PFGE is an assay for excluded volume effects.
