SARS-CoV-2, the coronavirus responsible for the disease COVID-19, contains an RNA genome surrounded by a protein capsid (coat) and a lipid envelope (membrane). Its spike proteins enable it to bind to ACE2 receptors of epithelial cells, allowing it to gain entry. Once inside, the virus hijacks the cellular functions and effectively turns the cell into a virus producing factory, with the synthesis of viral genome and proteins allowing virus particles to assemble and exit the cell. This overall process is representative of what viruses in general accomplish when infecting cells. Based on this information and your understanding of the definition of life, are viruses alive? Please explain. Include the following in your answer: Define the characteristics of life Identify which characteristics (if any) apply to viruses Identify which characteristics (if any) do not apply to viruses Explain your rationale for why viruses are or are not alive Your answer should be a paragraph of at least 4-5 sentences.
