Web16.2 Prokaryotic Gene Regulation. The regulation of gene expression in prokaryotic cells occurs at the transcriptional level. There are two majors kinds of proteins that control prokaryotic transcription: repressors and activators. Repressors bind to an operator region to block the action of RNA polymerase. Activators bind to the promoter to ... WebThe nucleus in living cells is sometimes indistinguishable from the cytoplasm unless the cell is stained. When stained, the nucleus appears darker than the surrounding cytoplasm. The cytoplasm is the region of the cell outside the nucleus. It contains fluid, ribosomes, the cytoskeleton, and, in eukaryotes, other membrane-bound organelles.
