Specialized Transduction Can Be Carried Out By

Question

Specialized transduction can be carried out by
A)any bacteriophage.
B)any temperate bacteriophage.
C)only those temperate bacteriophages that integrate into the host chromosome.
D)All of the choices are correct.

Accepted Answer

Specialized transduction involves the transfer of specific genes from the host chromosome into the phage genome during the lytic cycle of a temperate bacteriophage. These genes are then transferred to another bacterium upon infection by the phage. Only those temperate bacteriophages that integrate into the host chromosome can carry out specialized transduction, so answer choice C is correct. Answer choices A, B and D are incorrect because not all bacteriophages can perform specialized transduction.
