WebAug 7, 2009 · Operons (clusters of co-regulated genes with related functions) are common features of bacterial genomes. More recently, functional gene clustering has been reported in eukaryotes, from yeasts to filamentous fungi, plants, and animals. Gene clusters can consist of paralogous genes that have most likely arisen by gene duplication. Weba) Prokaryotes do not have a nucleus, while eukaryotes do. b) While prokaryotes grow and divide, multicellular eukaryotes develop and differentiate into different complex tissue c) Eukaryotic DNA, unlike prokaryotic DNA, is tightly packaged into chromatin. d) Eukaryotes and prokaryotes employ all of the same regulatory mechanisms, th
