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. And in this manner we transform our helper T cell into a factory that produces viral proteins and viral RNA molecules that ultimately causes the cell to lyse. And when it licenses, when it breaks open it releases many, many HIV agents that go on to essentially infect other helper T cells of our body. And in this method, what HIV does is it essentially destroys our population of helper T cells in our body and that weakens our immune system and leads to the Choired Immune Deficiency Syndrome.
