What is the main advantage of using modified vectors for gene delivery in plants and animals?

Options

  1. AThey are still able to use the mechanisms of pathogens to deliver genes
  2. BThey are no longer pathogenic to their hosts
  3. CThey are able to deliver genes of interest into humans
  4. DThey are able to transform normal cells into cancerous cells

Correct answer

B. They are no longer pathogenic to their hosts

Step-by-step solution

. Similarly, retroviruses in animals have the ability to transform normal cells into cancerous cells. A better understanding of the art of delivering genes by pathogens in their eukaryotic hosts has generated knowledge to transform these tools of pathogens into useful vectors for delivering genes of interest to humans. The tumor inducing (Ti) plasmid of Agrobacterium tumifaciens has now been modified into a cloning vector which is no more pathogenic to the plants but is still able to use the mechanisms to deliver g
