WebJan 19, 2024 · For example, the coronavirus responsible for the pandemic contains spike (S) proteins on its surface that bind to angiotensin-converting enzyme 2 (ACE2) receptors and thus infects host target cells. Moreover, the specificity of the binding determines the ability to infect and the host range of the viruses. WebThe criteria used for classifying viruses into families and genera are primarily based on three structural considerations: (1) the type and size of their nucleic acid, (2) the shape and size …
