Selfish operon
Webarchaea has been interpreted within the framework of the selfish operon concept, where the selfish character of these compact genetic elements make them prone to horizontal spread among prokaryotes (Lawrence, 1997, 1999; Lawrence and Roth, 1996) •Operons are often spread as a unit through horizontal gene transfer WebNov 27, 2024 · Recent work indicates that the selfish operon hypothesis can explain operon formation under appropriate conditions, and there is some evidence that these conditions obtain in natural contexts (Ballouz et al. 2010). Second, HGT might be able to explain the persistence of operons even if it does not explain their formation.
