Regulation in prokaryotes and eukaryotes

Regulation in prokaryotes and eukaryotes controls gene expression for proper cell function. In prokaryotes, it typically occurs at the transcriptional level using operons, which coordinate the expression of related genes. In eukaryotes, regulation is more complex and occurs at multiple levels, including transcriptional, post-transcriptional, translational, and post-translational. Mechanisms include transcription factors, enhancers, silencers, and RNA splicing, allowing for precise control of gene expression.
