Retroviruses have a long incubation period before active disease processes begin. Each of the multiple copies of the endogenous retrovirus was subtly different. Sometimes the genes of the retrovirus do not express their information immediately. Retroviruses slip genes into chromosomes at random, sometimes causing mutations that can make normal cells turn into cancers.

In the future, they might be of benefit in sheltering endogenous genes from retrovirus-induced transcription. Figure 4 illustrates the use of a replicationdefective retrovirus as a vehicle for gene delivery. The evolutionary relationship between retroviruses and retroelements is also becoming clearer. Retrovirus-like elements transcribe, their transcript is spliced by the host and two to three proteins required for transposition are translated from it. Cells were fixed 8 days or at other time points, as specified, after the addition of the growth factor or retrovirus.
