← Human Body & HealthWhat causes increased antibiotic resistance in a bacterial population within a hospital environment after only some bacteria acquired resistance via a plasmid?
A)Direct gene transfer by transduction
B)Conjugation-mediated plasmid replication
C)Horizontal gene transfer via conjugation✓
D)Transformation by naked DNA uptake
💡 Explanation
Horizontal gene transfer via conjugation spreads resistance rapidly because plasmids carrying resistance genes are transferred between bacteria, even across species, therefore, leading to a widespread increase in antibiotic resistance rather than solely relying on slower mutation and selection processes.
