Transcribing DNA to messenger RNA and translating that. In both eukaryotic and bacterial systems a protein either an activator or repressor binds to a region of the DNA called an operator in prokaryotes and a regulatory switch or enhancer in eukaryotes.

Pitx1 controls the expression of multiple genes not just.
These spines are important in the ocean for fending off large predators so why were they lost in freshwater populations. This is because the Pitx1 gene contains multiple regulatory switches that allow for transcription of that gene in multiple tissues. The expression of Pitx1 is important in various tissues because the Pitx1 protein is itself a regulatory protein that serves many roles in the development of the fish. Students may wonder why Pitx1 is expressed in such diverse tissues. Evolving Switches Evolving Bodies 1. GENE REGULATION IN DIFFERENT TISSUES As you saw in the film the presence or absence of pelvic spines in the stickleback fish is controlled by whether the Pitx1 gene is expressed in the pelvic tissue.
