PolyA_DB 2: mRNA polyadenylation sites in vertebrate genes.

abstract：:The tight-binding I12-X86 lac repressor binds to non-operator DNA in a sequence-specific fashion. Using the DNA of the E. coli I gene we have investigated these sequence-specific interactions and compared them to the operator binding of wild-type repressor. The specific, non-operator DNA interactions are sensitive to ...
