Please provide a general definition of a virus. Viruses can cause other issues, known as cytopathic effects. Provide 3 effects and discuss why that effect can be very damaging to the host.
Describe cytopathic effects of viruses and the possible results ofpersistent viral infections.
Explain how retroviruses function. Be sure to address the role of reverse transcriptase in the replication process of RNA virus.
