Quiz  /  NEET MCQ on Transduction

  • 1. 
    Through transduction when a recipient bacterial cell picks up bacterial DNA, then

  • the new DNA replicates every time the recipient undergoes multiplication
  • the DNA is destroyed
  • the DNA modifies to match/compliment that of the recipient
  • the new DNA should enter a new bacteriophage or it is lost

  • 2. 
    A specialized transducing phage that attacks an infected cell with lysogenic stage of the same virus produces

  • HFT
  • HFR
  • F
  • F`

  • 3. 
    This is the role undertaken by bacteriophage in transduction

  • episome
  • recipient
  • donor
  • vector

  • 4. 
    The ability of cells to uptake DNA fragments from the surroundings is known as

  • HFR
  • Competence
  • Fecundity
  • Fitness

  • 5. 
    Who discovered Transduction

  • Iwanowsky
  • Hayes, Lederberg and Woolman
  • Griffith
  • Lederberg and Zinder

  • 6. 
    This process involves transferring naked DNA fragments between bacteria

  • Vectoring
  • Transformation
  • Transduction
  • Conjugation

  • 7. 
    This is the virulence of viruses producing bacterial cell after infection if a specialized transducing virus attacks a healthy bacterial cell

  • Virulence depreciates
  • Equal virulence seen as the original one
  • More virulence than the original one observed
  • No virulence

  • 8. 
    It is ___________ when the phage tranduces those bacterial genes only which are adjoining to the prophage in the bacterial chromosome

  • conjugation
  • restricted transduction
  • specialized transduction
  • generalized transduction

  • 9. 
    This is incorrect regarding specialized transduction

  • observed in lambda phages such as K12
  • viral genome is incorporated in the bacterial genome
  • variety of genes can be transformed in this case
  • lysogenic viruses are capable of performing this

  • 10. 
    This virus is used for transduction

  • Lambda phage
  • T7 phage
  • T4 phage
  • T2 phage
