Bacterial Antibiotic Resistance is Frequently Conveyed By

Question

Bacterial antibiotic resistance is frequently conveyed by
A) A temperate bacteriophage
B) An R-factor plasmid
C) A replicon
D) A lytic bacteriophage
E) An intron

Accepted Answer

R-factor (resistance) plasmids contain genes for proteins that degrade antibiotics or alter antibiotic transport, thus conferring antibiotic resistance. They also carry transfer genes, which facilitate their intercellular transfer to other genomes.
