They have ability to synthesize nucleic acids and proteins
Antibiotics have no effect on them
Solution
Viruses are the microorganisms which injects a living host and remain as intercellular parasite. They inject their genetic material which replicates using host cell machinery and reform their structure and attain viable structure capable enough to affect other cells. They have ability to synthesize nucleic acids by replication. Antibiotics do not acts against virus as they are made up of polymorphic protein coat. Viruses have different type of symmetry like icosahedral and helical.
