Answer / Dhirendra Kumar Awasthi
"Multidrug resistance (MDR) primarily arises through the activation of stable genes encoding drug efflux pumps, also known as multidrug resistance genes (MDRGs). These pumps expel a variety of drugs from the bacterial cell, reducing their effectiveness. However, MDR can also arise due to mutations in genes encoding other types of transporters and through various chromosomal alterations."
