|
**Which type of horizontal transfer?
Transfer of DNA from donor to recipient cell by cell lysis.
Donor cell lysis and release of cell fragments DNA enters recipient cell and integrate into DNA
Naturally competent are capable of taking up this DNA without manipulation |
Bacterial TRANSFORMATION |
|
|
**Which type of horizontal transfer?
Transfer of DNA from donor to recipient cell mediated by a conjugative plasmid that encodes for transfer genes and sex pili
Significant for transfer of Antibiotic resistance
Require cell contact
Plasmid transfers from F+ (male) to F- (female) cell. Results in 2 F+ cells |
Bacterial CONJUGATION |
|
|
**Which type of horizontal transfer?
Transfer of DNA from donor to recipient cell by bacteriophage
Cell does lyse
DNA incorporated into chromosome called prophage |
Bacterial TRANSDUCTION |
