Do the same gene controls operate in bacterial cells and eukaryotic cells? Why or why not?
What will be an ideal response?
No. Three types of gene controls are: (1) control by histone organization of the DNA, (2) transcriptional control by regulatory proteins in operons, and (3) control of the transport of mRNA out of the nucleus. Those not found in prokaryotes are: (1) because the single, circular DNA of prokaryotes is not organized around histone proteins; and (2) because there is no nucleus in prokaryotes. Of course, (3) is very typical of prokaryotes; the same mechanism is not found in eukaryotes.
