What is one difference between gene regulation in prokaryotes and eukaryotes?

Prokaryotes do not store their genes in a nucleus like eukaryotes do.

All eukaryotes use operons to organize their genes while prokaryotes do not.

Eukaryotes transcribe genes in response to environmental stimuli while prokaryotes transcribe genes randomly.

Prokaryotes remove exons from mRNA before translation while eukaryotes translate the entire sequence of mRNA
