Gene Regulation: Operons and Epigenetics · Zoology

A key difference between prokaryotic and eukaryotic gene regulation is that eukaryotes:

Use operons as their primary regulatory strategy
Lack all transcription factors
Use epigenetic mechanisms
Regulate only metabolic genes

Show answer and explanation

Correct answer: Use epigenetic mechanisms

Eukaryotic gene regulation relies heavily on epigenetic mechanisms such as DNA methylation and histone modification. While prokaryotes primarily use operon-based transcriptional control, eukaryotes add these heritable chromatin-level layers of regulation.
