Conjugation, transduction, and transformation are the three main mechanisms for gene transfer between bacteria. Compare these three mechanisms in terms of how DNA is transferred
What will be an ideal response?
ANSWER: Conjugation involves the transfer of DNA from one bacterium to another via direct contact
between the donor and recipient cells. In transduction, a virus packages some bacterial DNA
into its capsid; when the virus infects another bacterial cell, it injects bacterial DNA from the
first cell into the second cell. In transformation, bacteria take up DNA pieces that are released
as other cells disintegrate.
