Study Notes
Gene Transfer in Bacteria
- Transduction is the process of transferring DNA from one bacterium to another with the help of a virus.
- Transformation involves the consumption of DNA fragments from the surroundings, which are then incorporated into the chromosomes of the bacterium.
- Conjugation is the bacterial equivalent of sex, involving the transfer of genetic material from one bacterium to another.
Conjugation Process
- During conjugation, a single strand of DNA from the F-plasmid is transferred from the donor cell to the recipient.
- The F-plasmid must be present in the donor cells during conjugation, but not in the recipient.
Transformation Process
- Transformation can only occur in bacteria that have entered a state of competence, which requires the activation of several genes expressing the appropriate proteins to acquire competence.
- Bacteria convert DNA from other bacteria of different species during transformation.
Plasmids
- Plasmids are large linear DNA molecules usually found in bacteria.
