WebJan 3, 2024 · Transduction is a common tool used by molecular biologists to stably introduce a foreign gene into a host cell’s genome. Transduction: Transduction is the process by which DNA is transferred from one bacterium to another by a virus. It also refers to the process whereby foreign DNA is introduced into another cell via a viral vector. WebIn a nutshell, a virus is a non-cellular, infectious entity made up of genetic material and protein that can invade and reproduce only within the living cells of bacteria, plants and animals. For instance, a virus cannot replicate itself outside the host cell. This is because viruses lack the required cellular machinery.
