Which of the following is wrongly matched in the given table:-   Virus Nucleic Acid 1) Pox virus ds DNA 2) Myxo virus ss RNA 3) TMV ss RNA 4) Adeno virus ss DNA

Which of the following is wrongly matched in the given table:-   Virus Nucleic Acid 1) Pox virus ds DNA 2) Myxo virus ss RNA 3) TMV ss RNA 4) Adeno virus ss DNA Correct Answer 4

Key Points
  • Virus is a microscopic, infectious agent that can multiply only inside living cells.
  • They are considered to be non-cellular biological entities as they lack cellular structures.
  • They are composed of a nucleic acid enclosed in a protein covering called capsid.
  • The nucleic acid present in the virus can be either DNA or RNA.
  • Viruses can be categorized based on their nucleic acids:
    • ds-DNA virus - They contain double-stranded DNA as their nucleic acid component.
    • ss-DNA virus - They have single-stranded DNA.
    • ds-RNA virus - They have double-stranded RNA molecule.
    • ss-RNA virus - They contain single-stranded RNA.

Important Points

  • The given viruses and their corresponding nucleic acids are:
    • Poxvirus - ds DNA
    • Myxovirus - ss RNA
    • TMV (Tobacco Mosaic Virus) - ss RNA
    • Adenovirus - ds DNA
  • In the given question, the adenovirus has been wrongly matched with ss-DNA nucleic acid.
  • Hence, the correct answer is option (4).

Additional Information

  • Poxvirus - They are a family of viruses that cause various diseases in humans and other animals that leads to skin lesions or nodules.
  • Myxovirus - This is a group of viruses that are responsible for diseases like influenza and mumps.
  • TMV - The tobacco mosaic virus infects tobacco and other members of Solanaceae family to cause mosaic-like discoloration in the leaves.
  • Adenovirus - These typically cause respiratory illnesses like bronchitis, pneumonia and also conjunctivitis.
