Tembung virus asale saka basa Latin, yaiku virion utawa venom sing tegese racun. Virus minangka organisasi sub-selular amarga ukurane cilik lan mung bisa dideleng nganggo mikroskop elektron. Malah bakteri sing paling cilik bisa kena infeksi virus. Virus reproduksi kanthi cara replikasi (reproduksi dhewe), ing sel inang. Kanggo replikasi virus mung asam nukleat sing dibutuhake. Materi sing dibutuhake kanggo sintesis protèin virus asalé saka sel inang utawa inang. Proses reproduksi virus dumadi saka limang tahap, yaiku adsorpsi, penetrasi, sintesis (gerhana), maturasi lan lisis. Adhedhasar definisi kasebut, virus digolongake minangka dudu makhluk urip. Ciri-ciri virus yaiku ora bisa nindakake metabolisme dhewe, ora bisa niru tanpa sel inang, ora tuwuh, lan ora nanggepi lingkungane. Virus bisa digunakake ing teknologi rekayasa genetika (manipulasi informasi genetik), contone kanggo terapi gen. Terapi gen minangka upaya kanggo nambah informasi genetik kanthi ningkatake susunan basa nitrogen ing untaian DNA ing gen.
