- Bacteria reproduce asexually, researchers rely on genetic transfer

7.1: Overview of genetic transfer in bacteria

- Genetic transfer is a process by which one bacterium transfers genetic material to
another bacterium
- Enhance the genetic diversity of bacterial species
- Three mechanisms to naturally transfer their genetic material
o Conjugation: direct physical interaction between two bacterial cells  donor and
recipient
o Transduction: a virus infects a bacterium and transfers bacterial genetic material
from that bacterium to another
o Transformation: genetic material is released into the environment when a
bacterial cell dies  binds to a living bacterial cell
