Prokaryotic & Eukaryotic Gene Expression
Prokaryotic transcription and translation occur simultaneously in the cytoplasm; regulation occurs at the transcriptional level. Eukaryotic gene expression is regulated during transcription and RNA processing, which take place in the nucleus, and during protein translation, which takes place in the cytoplasm. Further regulation may occur through post-translational modifications of proteins.
