In orthomyxovirus entry, the particle is taken into an endocytic vesicle and uncoating is helped by

  • A.reverse transcriptase released from the core
  • B.complete removal of the genome at the cell surface
  • C.an ion channel that acidifies the particle
  • D.digestion of the capsid by ribosomes

Answer: C

A channel embedded in the envelope lets protons in and the resulting acidification loosens the particle so the genome can be released. It is a good illustration that uncoating is not one mechanism but several, differing by family.
