Web7 de ago. de 2009 · Introduction. Operons (clusters of co-regulated genes with related functions) are a well-known feature of prokaryotic genomes. Archeal and bacterial genomes generally contain a small number of highly conserved operons and a much larger number of unique or rare ones [].Functional gene clustering also occurs in eukaryotes, from yeasts … Web11 de jan. de 2024 · Bacterial genes are typically grouped into operons defined as clusters of adjacent genes encoding for proteins that fill related roles and are transcribed into a single polycistronic mRNA molecule.
