 As part of the transformation process , the RecA protein interacts with entering single @-@ stranded DNA ( ssDNA ) to form RecA / ssDNA <unk> that scan the resident chromosome for regions of homology and bring the entering ssDNA to the corresponding region , where strand exchange and homologous recombination occur . Thus the process of homologous recombination during bacterial transformation has fundamental similarities to homologous recombination during meiosis .
