2. Transduction, the infection interceded move of DNA between microscopic organisms.  

3. Formation, the exchange of DNA starting with one bacterium then onto the next by means of cell-to-cell contact.

Kinetic to electric

Explanation:

The turbine blades turn because the water (possessing kinetic energy) pushes the blades. The kinetic energy in the blades turn the shaft, which is still kinetic energy (energy of movement), to power a generator. A generator has an input of kinetic energy and uses it to induce electrical energy.
