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 a type of protein. It prevents the transcriptional stages of genes which involved in the Lactose utilization. Lac Operon binds to the DNA at a particular site which is known as Operator. Operator is the downstream of the promoter and the upstream of the site of transcription.
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.
