Q. Consider the following statements regarding the benefits of Gene Editing:
1. It can be used to treat many human diseases & genetic disorders like HIV/AIDS, hemophilia.
2. It can slow down the spread of diseases by eliminating its means of transmission.
3. It can be used to bring to life extinct species.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 and 3 only

[C] 1 and 3 only

[D] 1, 2 and 3

Answer: D
Notes:

It is a type of genetic engineering in which DNA is inserted, deleted or replaced in the genome of an organism using artificially engineered nucleases, or “molecular scissors”.  

  • Human genome editing can be used to treat many human diseases & genetic disorders like HIV/AIDS, hemophilia etc. 
  • It could substantially bolster disease resistance in humans & increase life span. 
  • It could form the basis of highly efficient & cost-effective next generation antibiotics (based on bacteriophage viruses). 
  • Gene editing can be used to protect endangered species or bring to life extinct species. 
  • It can be used to grow healthier food (via fortification) and increasing harvest. 
  • It has the potential to slow down the spread of diseases by eliminating its means of transmission. E.g., Gene editing can be used to introduce sterile mosquitoes into the environment.
