A) The entire virion is taken into an animal cell, but only the viral genome enters E coli.
B) The entire virion enters E coli, but only the nucleic acid is taken up by animal cells.
C) The virion fuses to the bacterial cell membrane of E coli, while the genome is injected into an animal cell.
D) The virion randomly attaches to E coli, but viral binding to a specific receptor is required for entry into animal cells.
