Which among A-D is false regarding most DNA virus infections and most non-retroviral RNA virus infections? A. Once inside the host cell, RNA virus replication usually (though not always) occurs completely in the cytoplasm. B. The genome of DNA viruses generally must enter the nucleus of the host cell they infect. C. A (+) sense RNA strand produced by an RNA virus could serve as an mRNA and be directly translated into protein. D. DNA viruses typically are assembled in...

1-1. The SARS-CoV-2 is an enveloped virus, meaning it is surrounded by a bilayer of membrane that it acquires as it exits the host cell. a. What is the host membrane bilayer made of? b. What is the other main macromolecule that comprises the “fluid mosaic” model of a cell membrane? 1-2. To gain entry, spikes of the SARS-CoV-2 bind to angiotensin-converting enzyme 2 (ACE2) found in epithelial cells especially of the respiratory and oral passageways. As such, these cells...
