Question

Quizplus · Accepted Answer

Integrons are gene-expression elements that have the ability to collect resistance gene cassettes and are known for their mobility. They are responsible for rapid transmission of drug resistance and can be found in bacteria, particularly those that are pathogenic. Integrons act as gene capture systems that allow bacteria to capture and incorporate exogenous DNA containing antibiotic resistance genes, leading to the rapid spread of drug resistance. Therefore, integrons are a key factor in the development and spread of multidrug-resistant bacteria.
