Answer to Question #169773 in Cell Biology for Greg

Question

How do structural and regulatory genes differ in their arrangement in the genome in prokaryotes and eukaryotes?

Answer 1

Prokaryotic transcription and translation occur simultaneously in the cytoplasm, and 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.
