Aim: What is positive feedback of bacterial operons?
... Inducible enzymes usually function in catabolic pathways, digesting nutrients to simpler molecules. (lactose metabolism). Both repressible and inducible operons demonstrate negative control because active repressors can only have negative effects on transcription. ...

GENE REGULATION IN PROKARYOTES AND EUKARYOTES
... mRNA must be exported from the nucleus before it can be translated. This means that other factors being equal, protein synthesis in a prokaryote can be faster than in a eukaryote. It also means that the primary mRNA transcript can be processed before it is exported from the nucleus, with translation ...
