Phage mediated change in C. diphtheria is due to which of the following?
(A) Conjugation (B) Transformation (C) Transduction (D) None of the above
(C) Ans: C. Transduction(Ananthanarayan 10/e p59, 8/e p65-67; Jawetz 27/e p112).Phage mediated change in C. diphtheria is due to Transduction.In transduction, donor DNA is carried by a phage coat and is transferred into the recipient by the mechanism used for phage infection.Methods of transferMechanismNature of DNA transferredConjugationTransfer of DNA form one bacterium toChromosomal or plasmid DNAdegTransductionTransfer of DNA form one bacterium toAny gene in generalized transduction, only selected genes in specialized transductiondegTransformationTransfer of DNA from one bacterium toAny genedeg
