Popis: THE lac represser binds very specifically and tightly to the lac operator1–3. In conditions where the repressor binds to operator with a dissociation constant of 10−13 M, the binding of represser to DNA not containing the Escherichia coli lac operator (non-operator DNA) was less tight by several orders of magnitude3. Although weak, we thought this non-operator DNA binding could be highly significant and deserved careful study. We report here on the binding of lac represser to non-operator DNA from several natural sources and also to synthetic poly dAT.
