A 50-year-old man who recently immigrated to the USA from Russia develops fever, swelling of the neck, and difficulty swallowing. His vaccination history is uncertain. Examination of the throat shows a gray membrane across the pharynx. The pathogen responsible for this infection most likely acquires its virulence through which of the following genetic events?

A) Acquisition of a transposon
B) Chromosomal mutation
C) Conjugation
D) Recombination
E) Transduction


  #2

E - diphtheria

  #3

E-PLASMID MEDIATED

  #4

Can anyone pls explain choice E? FA says transduction=DNA transferred by a VIRUS from 1 cell to another...DNA jumping from 1 bacteria to another via PLASMIDS is a transposone...So maybe somebody could clarify that for me...Thanx

The toxin in Corynebacterium in acquired by a phage infection therefore only E is relevant.
