Study Notes

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.
