Or the integrated viral DNA may exert its influence upon the cellular genome and cause the cell to reproduce aberrantly, erratically, uncontrollably, thereby transforming it into a . . .

. . . cell. Or the viral genes may do nothing at all, may simply lie low—for years, perhaps—safe and undetected within the heart of the cell, until prompted once again to become active and produce more viruses, or a transformed cell, or both. What causes the activation isn't always entirely clear. There are many retroviral mysteries to be unraveled.
