Duke biomedical engineers discover bacterial DNA’s recipe for success

DURHAM – Biomedical engineers at Duke University have developed a new way of modeling how potentially beneficial packages of DNA called plasmids can circulate and accumulate through a complex environment that includes many bacterial species. The work has also allowed the team to develop a new factor dubbed the “persistence potential” that, once measured and computed, can predict whether or not a plasmid will continue to thrive in a given population or gradually fade into oblivion.
