Question

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

Explanation:

Transduction is a process of gene transfer in bacteria mediated by bacteriophages.

• Option a: Donor and recipient bacteria need to be close for bacteriophages to transfer genes, so this is required.
• Option b: Recipient bacteria need binding sites for bacteriophages to be infected and receive the transferred gene, so this is required.
• Option c: Natural competency is related to transformation (where bacteria take up free DNA from the environment), not transduction. So natural competency is not required for transduction.
• Option d: Bacteriophages are the vectors that carry genes from donor to recipient bacteria in transduction, so this is required.

Answer:

c) Natural competency
