The pseudorabies virus (prv) has played an important role for veterinary scientists in the development of genetically modified vaccines to prevent diseases. a. true b. false

The answer is true.

Pseudorabies virus (PRV) is a double-stranded DNA virus which has many non-essential genes. Non-essential genes can be replaced with genes that encode heterologous antigens but without deleterious effects on virus propagation. So, recombinant PRVs expressing both native and foreign antigens are able to stimulate immune responses and thus can be used as live attenuated vaccines.

the cell cycle is the final answer! : )
