The pellis will grab into another bacteria and get them close. The bridge will form
between them and the DNA will be transferred between them
The donor copies the DNA and transfers it to the recipient
The piece of DNA is a parasite. There is benefit for bacteria to transfer this material bc

+ means bacteria is capable of synthesize themselves
- Means they cannot make themselves
If you put them in minimal medium they will not grow because they are auxotrophic
Culture 3 is culture 1 and 2. They have colonies made in minimal medium.
There was transfer of one bacteria to the other
Auxotrophy – cannot grow on minimal medium
Phototrophic – can grow on minimal medium
• Not all strains can transmit their
