well-versed investigators describe in step-by-step detail a wide range of dna repair activities, from single act-alone repair proteins to complex repair systems. these practical protocols not only detail the various repair activities found in cells, but also demonstrate the use of dna repair proteins and systems as reagents in molecular biology and biotechnology. the techniques described here include mutation and polymorphism detection, which are useful in the search for disease genes and drug response genes, as well as for breeding and trait selection in animals and plants. compact and highly practical, dna repair protocols: prokaryotic systems provides expert guidance to both the dna repair researcher studying the fundamental aspects of dna repair and the applied researcher in human genetics and biotechnology.
