Where genetic material can be exchanged.
1 - A conjugation tube forms between a donor & recipient. An enzyme makes a nick in the plasmid.
2 - Plasmid DNA replication starts. The free DNA strand starts moving through the tube into the recipient bacteria.
3 - In the recipient cell, replication starts on the transferred DNA.
4 - The cells move apart & the plasmid in each bacteria forms a circle.
Advantage -> may contribute to genetic variation - in the case of antibiotic resistance genes, survival in the presence of these chemicals could be passed on.
