Options

  1. AAll are parasites
  2. BAll of them have helical symmetry
  3. CThey have ability to synthesize nucleic acids and proteins
  4. DAntibiotics have no effect on them

Correct answer

B. All of them have helical symmetry

Step-by-step 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.
