Study Notes
Plasmids in Bacteria
- Plasmids are small, self-replicating circular DNA molecules that are separate from the bacterial chromosome.
- The function of plasmids in bacteria is to provide genetic instructions for various beneficial traits, such as antibiotic resistance, that can be expressed by the host bacterium.
- An example of a trait that can be specified by plasmids is antibiotic resistance, allowing bacteria to survive in the presence of antibiotics that would otherwise be lethal.
