|
|
DNA that has been damaged by UV radiation typically form ? dimers that can be repaired by ? or light repair.
|
thymine
photoactivation |
|
|
DNA ? are light sensitive enzymes.
|

|
Transmission of genetic material in bacteria usually involves exchange of small pieces of ? in the form of ? and ? fragments.
|
DNA

|
|
In genetic transmissions conjugation is a ? form of transmission and transformation and transduction are ? forms
|
direct

|
|
? requires the attachment of two related species and the formation of a bridge that can transport DNA.
|
conjugation
|
|
|
? entails the transfer of naked DNA and requires no special vehicle.
