What do you know about bacterial transformation? Do you assume you can pass this quiz? Bacterial transformation is a horizontal gene transfer process by which some bacteria take up foreign genetic material (naked DNA) from the environment. The four bacterial transformation steps are competent cell preparation, the transformation of cells, cell recovery, and cell plating. Taking this quiz will put your knowledge of bacterial transformation to the test.
