The lac repressor functions as a tetramer and requires binding of all four sites before it releases because first it assures that the lactose level is high before the operon turns on for further steps.
<h3>
What is Lac Repressor ?</h3>

Lac repressor is made up of 2 DNA binding subunits which are composed of 2 monomers each and the monomers have particular 4 distinct regions.
