Which of the following is a feature of a lac repressor? Correct Answer It is a tetramer

The lac repressor is a tetramer. In this tetramer, two dimers are tethered together. This tetrameric structure of the lac repressor is an exception, as in most of the regulatory proteins the DNA-binding domain occurs in dimers.
