Now, once the viral DNA is synthesized, it moves into the nucleus of that helper T cell and an enzyme known as Integrase, shown in green, basically binds onto that DNA of that cell. It clips it and opens it at a certain position and it inserts, it incorporates that viral DNA into that original genome, original DNA of the helper T cell. And now this is an infected helper T cell. So notice in this case, this was purely brown. But now a small piece of that viral DNA shown in red has been integrated with that genome of our helper T cell. Now, now that we have incorporated the viral DNA into our DNA of the cell, when that DNA is used to synthesize mRNA, we're going to synthesize viral mRNA to produce viral proteins.
