Abstract

A method of efficiently sequencing multiple exons from complex genomic DNAs is disclosed. The methodology includes the use of bacterial and bacteriophage-derived artificial chromosomes (BBPACs) in novel gene trapping protocols. Targeted gene trapping by homologous recombination, and random gene trapping with the use of a transposon system are exemplified. Included in the invention are methods of preparing a gene map from BBPAC contigs, the resulting gene maps, methods of constructing a cDNA library from BBPAC contigs, and the resulting cDNA libraries.
