DNA profiling may help to identify terrorists

Well, we do have new techniques and technologies now, don't we? I think we should be investigating such things once more.

DNA does not change. It sort of creates templates which create reactions. But it is possible to block creation of those templates, temporarily, or permanently. At times, it may also fold the wrong way. At least logically. If that happens wrong reactions can occur and wrong chemicals may be released in the body. Similarly, over expression of something else may happen, which is what I suspect happens in the case of terrorists. How can those templates be blocked? I believe if we have something like serotonin to influence moods it must be happening at that level. Of course, this is mere speculation. But if we can get into this, each one of us can get personalized medication, and simultaneously find ourselves something that keeps us calm not to mention free from terror. Wouldn't that be nice?

@vandana7 It definitely would be nice and that is why I did volunteer my services to aid you in the research

Not really. Some people remain calm in whatever be the situation, whereas others snap. There has to be a physiological reasoning because after all we all are only chemicals.

@vandana7 - Yes, you have a valid point that there would be physiological reasons for odd behaviour but besides DNA, there would be some other factors, which when seen in its totality may bring about a clear picture about an extremist.

@dpk262006 ...I think those environmental factors that you are hinting at do lead to some modifications in the system. But any such modifications are temporary. These modifications give way under certain situations. Without the presence of such chemical modifications adverse behavior becomes faster and easier. I am asking for study of all such things. For example, we know of something called adrenaline rush, right? Our perception interpreted by our brain and associated with some feeling leads to that. Agreed? Effectively, some chemical reaction is happening. Exactly what is that? Now imagine DNA as a long template. Here is a small RNA going and telling it, that is what is happening there. What are we to do. So DNA says ok...copy this sequence and send it to so and so gland. Something like that..as far as I can understand DNA does hold some keys. If DNA is going wrong in sequence selection, something is blocking it. Serotonin is another chemical whose effect is now understood in the brain. So why not terrorist behavior? Fanaticism, fan like adulation, love, what does it chemically. :) Wouldn't you like to know? :)

@vandana7 Sorry I didn't get back to this sooner. I had to read more here to really get what you're driving at. I'm skeptical. I honestly think upbringing and environment have a great deal more to do with the potential for criminal behaviour than any genetic disposition. I'm all for a greater understanding of human genetics but I think as far as preventing criminal behaviour we'd be better served trying to improve everyone's social and economic situations to prevent the kind of stress that would lead to crime.

@koopharper ..I am not sure about upbringing and environment. It does affect to an extent, but it is pretty much like the tentative bonding of NH3 group in chemistry, or for that matter even water..which breaks down into ionic form. It helps yes, with layers and layers. Now let us look at the other end. If we are being prejudiced about a religion what environment are we giving? If we create wars and demolish cities and a living system, what environment are we giving? What sort of upbringing is possible when a child loses parents and siblings, or has injured parents or poor parents? While genetic predisposition may more may not be true, we do need to study that as well and wage war on that front if possible, because that is easier and more conducive. As I was saying if we know the problem, we can look for a cure. If the chemical that leads to aggressiveness can be found, then spraying something that counters it may be far more easier and effective than spraying napa bombs?

That is first admission that DNA has some role. :) I am trying to tell that here is a situation...DNA sequence A, B, C, D, and E are there aligned vertically. Then comes a chemical externally or triggered normally due to some action...like harsh sound you wince...so there is something in minor scale which folds part of DNA....E folds on D and only A, B, C, continue to be expressed. D and E interact for longer than they should and some new chemicals are formed or some chemicals are formed in excess...in the blood either because of over expressions of A, B, C, or because of interactions of D and E. This chemical is BAD. I am not sure it happens. It is just a theory I am proposing as simplistically as possible. We need to understand which chemicals are more and what causes them. And whether injecting more of them makes a person inhuman like losing a sense of right and wrong.

I am not suspecting DNA to be bad, though that is a possibility. I am saying DNA is malfunctioning, and that it can be made to malfunction, by letting some part of it express more and other part of it express less. When that happens, the person may become terrorist. What is the change in the body ..chemical composition. In the terrorist such thing may be happening more easily than ours. In any event, once we identify that terrorism is because of some chemicals or shortage of it in our bodies, we can all be asked to wear something like a watch which will give a beep indicating to us that we need to use some medication. I also believe that there is threshold for everybody meaning there is a point beyond which anybody and everybody can be a terrorist.

Yes, a comparative study of chemicals in the body ratio of chemicals in the body when shown some films or spoken to in any manner perhaps can shed light on many things about our physiology in which DNA may play some role, actively, or inactively.

I believe excessive troubling of a person can lead to heightened need for self preservation like in the wilderness. Instincts improve and so does offensive nature. We may not have to use those killing bullets at all. We may just have to fire something that contains some chemicals which calms the nerves. May be like DDT we may be spraying it off and on. Just some weird thinking. I am good at it, ain't I?
