What allows the membrane of the HIV and the membrane of the host to fuse? The virus capsid dissolves in the phospholipid bilayer of the host cell membrane The virus contacts proteins on the cell membrane of the host, and then the viral proteins undergo conformational changes The virus docks at a pore, which then pulls the virus into the cell membrane due to molecular attractions

What determines the host range of a virus? the proteins in the host's cytoplasm the enzymes carried by the virus whether its nucleic acid is DNA or RNA the proteins on its surface and that of the host

Briefly describe how the variola virus acquires multiple envelope membranes from an infected cell.

Describe a drug therapy that has been used for patients infected with SARS CoV2.  What does it target/disrupt – a part of the virus itself, a viral process, the host immune response?

Are viruses living? Why or why not? What does obligate intracellular parasite mean?   What does every virus have? What is the difference between capsomers and capsids?   What is the difference between a naked and enveloped virus? What are the benefits and disadvantages of each? How does each enter and exit a host cell?

All virus particles, in their infectious form, contain which of the following components? Choose all that apply. Group of answer choices Ribosomes Mitochondria Nuclei Cell membranes Nucleic acids encoding genes Protein capsids

Which of the following allows the AIDS virus, which contains RNA to insert viral DNA into the DNA of a host T-cells after the AIDS virus enters the cells? o Receptor proteins located on the surface of the virus o Reverse transcriptase, an enzyme encoded by the virus o The phospholipids found on the envelope of the virus o The protein that makes up the capsid of the virus
