Virus Composition
- A virus is composed of genetic material (either DNA or RNA) surrounded by a protein coat called the capsid.
Virion
- A virion is a complete, fully assembled virus particle that is capable of infecting a host cell.
Capsid Function
- The capsid provides protection to the viral genetic material and helps the virus to attach to and enter the host cell.
Host Cells
- Viruses can infect a wide range of cells, including animal cells, plant cells, and bacteria.
Role of Virions
- Virions play a crucial role in initiating infection by attaching to and entering host cells, releasing their genetic material, and starting the replication process.
