What type of virus has the ability to transform normal cells into cancerous cells?

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 ge
