DH5alpha is mutant in recA

The post-doc sent me a list she's compiled of the experiments we're planning and the genotypes of the E. coli strains we'll use.  So far I've just glanced at them, but I noticed that one of the strains used for recombination is recA.  This means that the protein responsible for almost all homologous recombination is missing, so recombination shouldn't happen!  We'll have to get this sorted out asap.
