How will the processes of transformation, transduction, and conjugation be similar?

In what ways will the processes of transformation, transduction, and conjugation differ?

Answer 1

Similarity: in all three processes, bacterial cells of like or unlike species exchange genetic material

Differences: conjugation does not rely on a virus to facilitate the gene transfer. Bacteria have genes outside of the bacterial chromosome structure

Answer 2

Gene transfer refers to the movement of genetic information between organisms. Vertical gene transfer passes genes from parent to offspring.

Lateral gene transfer passes genes to other cells in the same generation. It occurs in bacteria by transformation, transduction, and conjugation.

Bacterial transformation was discovered in 1928 by Griffith, who showed that a mixed culture of live rough and heat-killed smooth pneumococci could produce live smooth pneumococci capable of killing mice. (Black)

How could dead bacteria give genes to the live bacteria?

The dead one left DNA behind which was picked up by the alive bacteria, changing it so that it could kill.
