Answer 2

Retroviruses are disarmed before used to deliver desirable genes into human cells because in animals, they have the ability to transform normal cell into cancerous cell.

Explanation:

• Retroviruses are RNA viruses which have Ribo Nucleic Acid as their genetic material rather than Deoxy Ribonucleic Acid (DNA).  

• They are used as a vector to deliver the desired gene in the target cells in gene therapy.

• Retroviruses mediated gene transfer is the most preferable because of their affinity and infectivity towards the target cells.

• Before using as a vector , the disease causing genes are  removed/destroyed from the retroviruses.

• The deleting/removing pathogenic genes are called as disarmed.
