Thanks! Still, the article does not back the claim of the parent. The citation that is given for the horizontal gene transfer in herpesvirus states the following:
> herpesviruses are known to capture host genes to evade host defenses. [0]
That still sounds like a one-way gene transfer, and in no way an 'insertion into your DNA to stay dormant' as parent claims.
