Well, arguing with you makes no sense.
First it is not a drug but a kind of "gene therapy" (actually it is not, but it is much closer than a 'drug')
The human body is not a cell nucleus. For example, if this drug triggers an allergy response, then you have both harm and the destruction of the drug before it can do something useful.
Good point, now you made perfectly clear why the treatment we are talking about: is not a drug.
And you emphasize that you are not interested in science, otherwise you would not write such nonsense.
Hint: reading up about how this stuff works is less then 8h, you can read every day 1h and after a week you perhaps know more than me about DNA/RNA, mRNA, siRMA etc.
But unless you invest at least some basic "reading up" you simply don't qualify for topics like this.
For example, if this drug triggers an allergy response how should an siRNA particle trigger an allergic response? Hu? Science Fiction? Note: it is not a drug, regardless how retarded you like to define it.
