An abortive infection is one in which

  • A.the cell lyses before the virus attaches
  • B.the genome integrates permanently
  • C.progeny are produced but cannot leave the cell
  • D.the virus enters but no progeny are produced

Answer: D

The virus gets in but the cell cannot support some necessary step, so the cycle stops and nothing infectious is made. Such a cell may still be damaged or altered, which is one route by which a non-permissive infection contributes to disease.
