Question

gene expression and gene regulation quick check
what is one difference between gene regulation in prokaryotes and eukaryotes? (1 point)
prokaryotes do not store their genes in a nucleus like eukaryotes do.
prokaryotes remove exons from mrna before translation while eukaryotes translate the entire sequence of mrna.
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.

Explanation:

• Prokaryotes have no nucleus, so their genes are not stored in a nucleus like in eukaryotes.
• Prokaryotes do not remove exons (they have no introns to splice out in the first place, while eukaryotes process mRNA by removing introns).
• Operons are mainly a prokaryotic feature (not all eukaryotes use operons, and prokaryotes often do).
• Both prokaryotes and eukaryotes transcribe genes in response to environmental stimuli (not randomly in prokaryotes).

Answer:

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