Virhes
Virhes, also known as viruses, are small infectious agents that replicate only inside the living cells of an organism. They are composed of genetic material, either DNA or RNA, enclosed in a protein coat called a capsid. Some viruses also have an outer lipid envelope. Viruses are obligate intracellular parasites, meaning they cannot replicate outside of a host cell. They infect a wide range of organisms, from bacteria and archaea to plants, animals, and even humans.
Viruses are classified based on their genetic material, structure, and the type of host they infect. They
The study of viruses is known as virology. Virologists study the structure, function, replication, and evolution
