Gene Transfer Facilitates Drug Resistance

Gene Transfer


Diagram showing how gene transfer facilitates the spread of drug resistance.

Diagram showing how gene transfer facilitates the spread of drug resistance. Bacteria multiply by the billions. Bacteria that have drug-resistant DNA may transfer a copy of these genes to other bacteria. Non-resistant bacteria receive the new DNA and become resistant to drugs. In the presence of drugs, only drug-resistant bacteria survive. The drug-resistant bacteria multiply and thrive.
