Illegitimate recombination is a natural process which was first found to be present within E. coli.A 700-1400 base pair segment of DNA was found to have inserted itself into the gal and lac operons resulting in a strong polar mutation. The most common form is general recombination, which usually involves a reciprocal exchange of DNA between a pair of DNA sequences.It occurs anywhere on the microbial chromosome and is typified by the exchanges occurring in bacterial transformation, bacterial recombination, and bacterial transduction.
