For uncoating, viruses use

  • A.Specific receptors
  • B.Lysozyme
  • C.The mechanism called viropexia
  • D.The synthetic machinery of host cell

Answer: B

Correct answer: Lysozyme

Uncoating is the removal of the capsid so that the genome can be expressed. It is done by the host’s own lysosomal enzymes once the particle has been taken into a vesicle - the virus supplies nothing for the purpose. Receptors are used in attachment, and viropexis is the engulfment step that precedes uncoating.
