(Explain your answer.) a. eukaryotic cells are much smaller b. in a multicellular eukaryote, different cells are specialized for different functions c. prokaryotes are restricted to stable environments d. eukaryotes have fewer genes, so … WebMar 31, 2024 · The expression of a gene is a highly regulated process. Whereas regulating gene expression in multicellular organisms allows for cellular differentiation, in single-celled organisms like prokaryotes, it primarily ensures that a cell’s resources are not wasted making proteins that the cell does not need at that time.
WebControl of Gene Expression in Prokaryotes 1 Control of Gene Expression in Prokaryotes How do prokaryotes use operons to control gene expression? Why? Houses usually have a light source in every room, but it would be a waste of energy to leave every light on all the time, so there are switches to turn off the lights in rooms that are not … WebThe 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 enhance the binding of RNA polymerase.
