Influenzа viruses cоntаin аn RNA genоme surrоunded by a protein capsid (coat) and a lipid envelope (membrane). They rely on two surface proteins (haemagglutinin, HA, and neuraminidase, NA) to bind to host cell receptors to gain entry. Once inside a cell, influenza viruses hijack the cellular functions and effectively turn the cell into a virus-producing factor, 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, including in your answer specific definitions of what it means to be alive, and addressing whether or not these apply to viruses.
