1.In early March, it was reported that two main strains of SARS-CoV-2 had been identified, termed S and L, with the S type being the less virulent ancestral form representing about 30% of prevalence and the more virulent L type having descended from the S type and representing about 70% of prevalence. However, the prevalence of the more virulent L type seems to have decreased after early January, and it is thought that this resulted from human intervention against this...

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...

5.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 are susceptible to infection by SARS-CoV-2. ACE2 is a protein
consisting of multiple alpha-helices that is embedded in, and
spans, the membrane. What is this type of protein called, and what
structure do the alpha helices represent?
6.Following binding of spike proteins to ACE2, SARS-CoV-2 likely
gains entry into the cell either...
