All viruses can cause cancer.

Which of the following is true of how a virus can cause cancer?

Retroviruses like HIV must carry __________________ in the virus particle to convert their RNA into double stranded DNA once in the host cell.

Why is a virus called an “obligate intracellular parasite?”

The host range of a bacteriophage is determined by

Segmented viruses are capable of undergoing genetic reassortment when they infect a host cell.  A.  Explain how genetic reassortment can occur to cause antigenic shift in a virus.  B.  This is the process that can produce unique viruses such as the H1N1 strain of Influenza that contains human, avian, and swine influenza genetic material.  Why are these new viruses such a threat to us?

To what receptor does SARS-CoV-2 bind on human cells?
