Viral DNA Insert
Name: Jackie M.
What can happen if a copy of viral DNA is inserted into
the human chromosome?
Here is a short list:
Variety of minor to major cellular disfunctions
Latency of the viral genes
Expression of viral genes

This actually happens each time you have a viral infection. But in some
viral infections, the viral nucleic acid is cut out again and is repackaged
into new virus. In other types of viral infections, the viral DNA inserts
itself into the host DNA for an extended period of time. Some scientists
have proposed that the origin of the junk DNA in the human genome is
inactivated viral DNA from past viral infections down the millenia.
