Answer- N- nucleocapsid and s-spike SARS-COV2 protein are phosphorylated.
The nucleocapsid protein (N-protein) is a structural protein that binds to the coronavirus RNA genome, thus creating a shell around the enclosed nucleic acid.
The spike protein (S-protein) performs two primary tasks that aid in host infection: 1) mediates the attachment between the virus and host cell surface receptors, and 2) facilitates viral entry into the host cell by assisting in the fusion of the viral and host cell membranes.

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...
How could the specific proteins (S, E, M, and N) on SARS-CoV-2 be useful targets for diagnosis? (1) For treatment? (1) What technologies or molecular diagnostics/therapeutics would be useful? (1)
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...
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...
