tokens: By examining the effects of the DinI protein on RdgC - mediated inhibition of RecA activities , it was concluded that the potent effect of RdgC in the inhibition of strand exchange did not primarily reflect a displacement of RecA in the nucleoprotein filament by RdgC , but instead a binding of RdgC to the dsDNA substrate so as to make it unavailable to the filaments for strand exchange ( 1 ) .
