Solution
The correct option is A Retrovirus
- Retroviruses are RNA containing viruses that replicate itself by first reverse-coding its genes into the DNA of the cells it infects. Once transformed from RNA to DNA, the viral DNA can be integrated into the genome of the infected cells.
- They are in animals have the ability to transform normal cells into cancerous cells. Scientists have transformed these pathogens into useful vectors for delivering genes of interest to humans.
- Retroviruses have been disarmed and are now used to deliver desirable genes into animal cells. So, once a gene or a DNA fragment has been ligated into a suitable retroviral vector it is transferred into a bacterial, plant or animal host (where it multiplies).
So the correct answer is option C.
