Question

g Both transduction and transformation establish that DNA is the genetic material of most living organisms. Both processes involve transfer and expression of DNA from cell to cell. What then is the difference between the two processes: Question 27 options: transduction is mediated by a phage while transformation requires a plasmid Both processes are mediated by a virus transformation is accomplished by a virus, and transduction is carried out by a bacterium transformation is carried out by random uptake of DNA, and transduction by a bacterial virus none of the choices are correct

Answer 1

Answer:

transformation is carried out by random uptake of DNA, and transduction by a bacterial virus

Explanation:

Transformation and transduction are two of the three processes bacteria uses in genetic recombination (the third being conjugation). As rightly stated in the question, both processes establish that DNA is the genetic material of most living organisms and they both involve transfer and expression of DNA from cell to cell.

However, both processes are different in the way they get the foreign DNA into the bacteria cell.

- Transformation involves the random uptake of foreign extracellular DNA by the host bacterial cell.

- Transduction involves the transfer of foreign DNA into a bacteria cell via a virus called BACTERIOPHAGE. N.B: A bacteriophage is a virus that infects a bacteria host.
