Antibiotic resistance in bacteria evolves through natural selection where mutated bacteria survive treatment, reproduce, and transfer resistance genes, sometimes via bacterial conjugation.
Antibiotic resistance in bacteria evolves through natural selection: naturally mutated resistant bacteria survive antibiotic treatment, reproduce, and pass on resistance genes, often aided by bacterial conjugation.
