Inducer and repressor

WebWhat is inducer and repressor? Function. Repressor proteins bind to the DNA strand and prevent RNA polymerase from being able to attach to the DNA and synthesize mRNA. Inducers bind to repressors, causing them to change shape and preventing them from binding to DNA. Therefore, they allow transcription, and thus gene expression, to take … WebFunction.

It is termed as Inducer. Repressor : The repressor of the operon is synthesized (all the time constitutively) from the gene. WebThe lac operon is considered an inducible operon because it is usually turned off (repressed), but can be turned on in the presence of the inducer allolactose.
