Question

which of these is not required in transduction? click the view theory button to get some guidance with the question.
a) natural competency
b) bacteriophages to carry the gene from donor bacteria
c) donor and recipient bacteria must be located close together
d) binding sites for bacteriophages on the recipient bacteria

Explanation:

Transduction is a bacterial gene transfer mechanism mediated by bacteriophages. Bacteriophages (option b) carry donor DNA. Recipient bacteria need binding sites for phages (option d). Natural competency (option a) is for transformation (DNA uptake from environment), not transduction. Donor - recipient proximity (option c) isn't needed as phages mediate transfer over distance. So natural competency is not required.

Answer:

a) Natural competency
