Editing Integron (section)

'''Integrons''' are genetic mechanisms that allow bacteria to adapt and evolve rapidly through the stockpiling and expression of new genes.<ref>{{Cite journal|title=ASMscience {{!}} The Integron: Adaptation On Demand|url=http://www.asmscience.org/content/journal/microbiolspec/10.1128/microbiolspec.MDNA3-0019-2014|doi=10.1128/microbiolspec.mdna3-0019-2014 | volume=3|year=2015|journal=Microbiology Spectrum | last1 = Antonio Escudero | first1 = José | last2 = Mazel | first2 = Didier | last3 = Nivina | first3 = Aleksandra | last4 = Loot | first4 = Céline|issue=2|pages=MDNA3–0019–2014|pmid=26104695| url-access=subscription }}</ref> These genes are embedded in a specific genetic structure called [[gene cassette]] (a term that is lately changing to integron cassette) that generally carries one promoterless [[open reading frame]] (ORF) together with a recombination site (''attC''). Integron cassettes are incorporated to the ''attI'' site of the integron platform by [[site-specific recombination]] reactions mediated by the integrase.
