    Something I've always wondered about, I know certain viruses can alter DNA of surrounding cells and also alter themselves through mutation. The question is will we ever be able to alter DNA to the point where we could change things like hair color, or perhaps correct certain genetic related predisposition to disease. I don't think we will ever be able to change a persons overall look as that's something you grow into, not something that's constantly updated. Bone for example I don't think would just change shape based on genetic changes. I could be wrong.

    Would also be interesting if we could alter aspects of a person to allow them to build muscle faster, or perhaps increase the capabilities of their brain during early development. That opens up a whole new can of worms with issues like genetically engineered children.

    I'm more curious as to what genetic alteration can do for those that are already grown. Could it help with obesity for example.

    Well, I don't think the editing of people will ever happen. If there is genetic modification, I believe it will take place just after conception.

    I doubt they will use a virus though. It seems like, if you want to change the regime of some small island in the pacific, you nuke it. Sure, it will change the regime, but it will change some other stuff too.

    I think they manufacture enzyms, molecules containing information on how a cell should be structured. This is, in a way, also how a virus is constructed, but a virus is a bit more complex (it has that Protein shell and stuff).

    I believe in genetic enhancement. AIDS can literally be killed in one generation by genetic enhancement. The chance of cancer can be reduced by genetic enhancement. We can eliminate various terminal, genetical illnesses in one generation.

    You see, I see evolution not as improvements. I see it as refinements. As a pebble that is carried by a river for millions of years, sharpened to perfection, our bodies become better adapted to our environment. We will soon be able to influence that adaptation. We will soon be able to create, not an ├╝bermensch, not a homo universalis, but a race that will enjoy life better than us. That will be better capable of enjoying the planet than we are.

    ||Imagine we can reduce the level of testorone in men. Imagine we can create a female-like man, with the characteristics of man, but without many of his base instincts. No more aggression, as this is no longer needed. Imagine we could eliminate war.

    Personally, I believe genetic experiments on people are worth dying for. I believe they are worth killing for.||

    I think it's highly likely that gene therapies will be developed that not only cure hereditary diseases (via germline therapy) but also alter appearance. Once we have a handle on the exact genes that control, say hair color, then it's only a matter of applying already understood techniques to deliver the alterations to the DNA.

    I can conceive of a time where you can take on designer genes for personal appearance. Want to look like Pamela Anderson? Just take an injection or pill that delivers the virus that will overlay her genetic code upon yours. Same for those that want the award winning build of Arnold Schwarzenegger. Of course, you still have to do all the work they do to build and maintain that body.

    I'm sure they will have it in time. It seems too much like playing God to me, but it will happen. They already know what to do, just not how to do it.

    There are GMO's. Would that count? With GMO's, they take the DNA of one thing and splice it with another's. I think that's how it works.

    I was thinking more along the lines of taking an existing organism and altering it in some way, say take my Golden Retriever and make it into an Irish Setter

    Hmmmm. I'm not sure, but when that happens, there will be no more birth defects, because they can make people perfect at birth, or even before.

    Naaa, they will screw up from time to time and make horrible monsters. Bound to happen.

    Yeah, I had to watch it for Biology back in highschool. Good movie.

    I do not think we will see the significant effects of DNA manipulation for some time yet. The initial work done with the splicing of single genes will affect hereditary disease and perhaps simple traits like eye color, however the complex interaction between genes and environmental factors such as hormones, will likely produce a significant number of screwups before we are in limited control.

    I think we will get plenty of action in our very own unmanaged lab - the Olympic Games. Watch this space for some genetic experiments over the next few years as we get social climbers sacrificing themselves for the rest of humanity.

    The big question is what mistakes will they make that have impacts that they never thought of, perhaps unlocking concepts or biological structures we never dreamed would exist. Many great discoveries were made out of mistakes, or side effects. Time will tell.

    Its more important to think about the impacts and results of screw ups. Did anyone see The Fly? There are several cases on the net of attempted Gene Therepy that resulted in death!

    DNA technology is an amazing thing. In many labs, we regularly clone, or knockout genes of interest. Various virus' or vectors are used to transfect genes of interest into other types of cells. It is possible to make all kinds of wonderful changes and learn about various systems!

    The thing is you have to really understand all of the viariables so that you don't get the results of the article listed above.

    Some good reading on the posted link,

    I think it's only a matter of time before they figure out how to do it right, it may end up being nano technology or something along that line that ultimately leads to success. For now I'm sure we'll have a ton of screw ups, I don't however think "The Fly" is a real possibility. The genetics just wouldn't survive.

    I'm sure that there is some way it can be altered. I'm sure that radiation will alter DNA.

    Like the Hulk? Or could the Spider Man incident ever happen?

    Maybe if you stick your head in the Microwave, you'll alter it somehow (Meant as joke, not serious)

    Radiation does alter animals to some extent. I don't know if the animals have offspring and if deformities are passed on. I really don't know.

    If DNA is altered in the parent, there is a 1:2 chance for everyone of the changes going onto the child (if those changes are on different chromosones), if the other parent does not have these changes.

    Radiation can change a little in the DNA, and it can change a lot in DNA. Although it's statistically unlikely, it is possible that a bacteria is changed in such a manner that it will start dividing and grow into a human.

    It's not neccesary to stick your head in a microwave. Each moment we spend outside, we are subject to cosmic radiation, and radiation from the Sun, both can change our DNA.

    Cancer is one of the prime examples of changing in DNA. And viewed by most as a negative change. It means that the cell is altered in such a way that it divides so much it seizes to function. Now, it is statistically unlikely that someone will get cancer, but if you multiply that with all the factors human beings are influenced by these days, and remember that people feel tanning is so important, you get to the percentage of (skin-)cancer patients as we are seeing them today.
