What is fallacy or weakness of practice in the following idea ?
shouldn't DNA sequencing make it a fast track to figuring out how to disarm incurable viruses ,such as HIV ? Sequence the DNA in the virus, and then synthesize a medicine that has a marker for the virus based on some unique sequence ;and that same medical molecule substitutes itself somewhere in the DNA of the virus and changes the sequences of the virus DNA so that the virus DNA cannot use the machinery of the host's cellls to replicate the virus ???
