Genomic DNA libraries.
Genomic DNA libraries are almost always screened by hybridization using a radioactive nucleic acid probe. Since this approach is essentially independent of a particular vector or type of target DNA, the main problem faced when considering creation of a genomic DNA library is simply generating a large enough number of recombinant DNA clones. The basic strategies used to address this problem have included both minimizing the number of clones necessary by incorporating large fragments of genomic DNA, and maximizing cloning efficiency by using vectors based on bacteriophage lambda. This unit discusses the appropriate numerical considerations for both ordinary genomic DNA libraries and subgenomic DNA libraries, and then describes a limited number of appropriate vectors.
