A protein found in Salmonella bacteria can exist as either a dimer that binds DNA and represses transcription of the gene encoding the protein or as a monomer that does not bind DNA.  At lower temperatures (28 °C), the bacteria expressed the protein at lower levels than at higher temperatures (37 °C).  These findings are most likely evidence of:A.disruption of primary but not tertiary structure at 37 °C.B.disruption of quaternary but not primary structure at 37 °C.C.alteration of both secondary structure and quaternary structure at 37 °C.D.alteration of neither secondary nor tertiary structure of at 37 °C.Submit
