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.

<h3>What is meaning of Extinction?</h3>

Extinction is the final phase of a sort of creature or a taxon—typically a species. Although the ability to reproduce and bounce back may have been lost earlier, the death of the last member of the species is typically considered to be the moment of extinction.

Determining this point is challenging because a species' potential range may be quite wide, and is typically done after the fact. Due to this problem, there are phenomena like Lazarus taxa, in which a species that was thought to be extinct suddenly "reappears" after a period of apparent absence (usually in the fossil record). Estimates place the number of extinct species at over five billion, or more than 99% of all species that have ever existed on Earth.
