A virus is an infectious agent made up of nucleic acid (DNA or RNA) wrapped in a protein coat called a capsid. Viruses have no nucleus, no organelles, no cytoplasm or cell membrane—Non-cellular This is why it does NOT belong to any kingdom. vs

Viruses have either DNA or RNA but NOT both. Viruses with RNA that transcribe into DNA are called retroviruses. Viruses are parasites—an organism that depends entirely upon another living organism (a host) for its existence in such a way that it harms that organism. HIV Infected Cell (This is the reason why HIV is so incurable. ) A flea is a parasite to a dog and is harmful to the dog.

Certain viruses can only attack certain cell types. They are said to be specific. Example: The rabies virus only attacks brain or nervous cells. Surface Markers Virus Receptor Sites It’s like the pieces of a puzzle. The ends have to match up so only certain pieces fit. Cell

Importance: *Harmful Causes disease—pathogenic Disease producing agent—pathogen Human Diseases: Warts, common cold, Influenza (flu), Smallpox, Ebola, Herpes, AIDS, Chicken pox, Rabies Viruses disrupt the body’s normal equilibrium/balance Viruses can be prevented with vaccines, but NOT treated with antibiotics. (antibiotics treat bacteria) Beneficial: Genetic Engineering—harmless virus carries good genes into cells.
