Virioni
Virioni are virus particles, also known as virions, that serve as the infectious units of viruses. They are composed of genetic material—either DNA or RNA—encapsulated within a protein coat called a capsid. Some virions also possess a lipid envelope derived from host cell membranes, which is embedded with viral glycoproteins essential for attachment and entry into host cells.
The structure and composition of virions vary widely among different virus families. Non-enveloped virions typically have
Virion size ranges from approximately 20 nanometers to over 300 nanometers, depending on the virus type. They
The study of virions is fundamental in virology, diagnostics, and vaccine development. Understanding their structure aids
In summary, virioni are the extracellular, infectious particles of viruses that play a critical role in the
