BacteriaVirus Ribosomes (Molecular protein synthesis machine) PresentAbsent Enzymes:YesYes, in some Nucleus:No Can cause disease?Yes Infection:LocalizedSystemic How is it treated?:AnibioticsVaccines prevent the spread and antiviral medications help to slow reproduction but can not stop it completely. Beneficial?:Question of the week
6
