WebBacteria must exchange DNA with one another to survive. Transformation: Bacterial transformation occurs when bacteria take up fragments of DNA from their surrounding environment. Transduction: This kind of sexual reproduction occurs when a virus introduces foreign genes into the bacterial cell. WebAlthough it is easy to see how prokaryotes exchange genetic material by HGT, scientists initially thought that this process was absent in eukaryotes. After all, prokaryotes are but single cells exposed directly to their environment; whereas, the multicellular organisms' sex cells are usually sequestered in protected parts of the body.

At 0.1–5.0 µm in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10–100 µm (Figure 3.7).
