is it possible to change one's DNA(temporal)? if so how?

You cant change it temporarily, but you can change it for good. this can either happen naturally (like sickle cell anemia) or it can by artificially; this is mainly because of excess radiation (this is harmful...very)\ni would advise you dont try changing it\nthere is another way but this involves viruses, the DNA wanted and transplant...

I just want to point out the fact that xaviar's and gradwrkout's answers are both very good.  Identical twins are spawned from a single set of DNA, so in theory, they are completely identical.  Some cells will vary due to mutations during DNA replication and other DNA mutating events, but mostly they will be identical.\n\nHowever, epigenetics can change throughout a person's lifetime, without altering the actual base-pairs of DNA.  Epigenetic changes include DNA CpG methylation, which can silence certain genes, and is common in certain cancers.  Another example of an epigenetic change has to do with chromatin.  Chromatin is what DNA is called when it is bound to histone core proteins.  When people talk about chromosomes, the chromosomes are always bound to histone.  The histone cores have little protein tails that can be altered in certain ways, which affects when a gene can be transcribed/translated.  Epigenetic changes can occur based on how you live your life-- if one twin lives in california and the other in london, the differences in their lifestyles will reflect in epigenetic changes.  Everything from diet and exercise to sleeping, etc, affects epigenetics.\n\nSo to answer the question, yes, their DNA is essentially identical, but over the course of their lifetimes, epigenetic changes can make them significantly different.  Also, just fyi, epigenetic changes are heritable.

Nope this is not possible. Although it would be nice, wouldn't it? No more expensive tests and laboratory procedures.... :-)

It is impossible as far as we can tell. Jurassic Park was a story. If anyone has been able to obtain dinosaur DNA, and that is still very much in dispute, the amount the have found is miniscule. Trying to reconstruct a dinosaur from what we have is literally like trying to physically reconstruct New York City from half a page ripped out of a telephone directory. And that is not an exaggeration. We have next to no genetic information, we have absolutely no information about the way that information was configured. We have no information about how to incubate the creature if we did create it. \n\nThose aren’t problems that can be overcome by technology. It’s not a case of retrieving the information somewhere that it’s hidden as with the human genome project. The information simply doesn’t exist. We have absolutely no way of ever getting that information ever again. \n\nThe only vaguely plausible method would be to evolutionarily ‘regress’ living descendants of dinosaurs such as birds. That’s so far outside our ability at the moment that it’s almost pure science fiction, but it isn’t actually physically impossible the way that using fragmentary DNA is.

It is entirely possible, however we are more than just the product of our genetic code, the clone would be a completely different individual. But although it possible, it is illegal to experiment with cloning of human beings. However, it is a matter of time before someone breaks that law if they have not done so already. Then again maybe they have done it in a country like China that in most instances would ignore international law.

No its impossible. The DNA is completely different, and plus cloning was banned by the Geneva Convention a couple of years ago I believe. But if your like the other groups and you want to try it, have at it. But if you do clone it together, dont tell the press or you might just end up going to prison.

You can't. It's set by your genes.

I gave a lecture on this recently and have had first hand experience with this technology in a lab, so let me give you a brief and easy summary to take with you about this topic about Recombinant DNA Technology:\n\nIn order to clone you need 2 things: Bacterial DNA (the circular form called a "plasmid"), and the DNA you want to clone (be it human, mouse, plant, other species etc)\n\nThen you will need to cut the Bacterial DNA with enzymes called "endonucleases" that work like scissors. (So imagine a circle and I take a pair of scissors and cut the circle at some point in it, b/c I want to insert the foreign DNA (non native DNA) where I had cut.) I will have to do the same with the foreign DNA and have endonucleases cut OUT the particular piece i want cloned. \n\nThen we can put the two pieces together, the cut circular plasmid DNA from the bacteria, and the CUT out piece of foreign DNA. \n\nWhen we put the two pieces together it is called "ligation", and it is done as a reaction in a tube with enzymes inside that "glue" the "sticky ends" of the bacteria DNA to the foreign DNA. \n\nAfter the reaction normally done in a 16 deg. Celsius water bath, we now will have "circular" plasmids with our Foreign DNA inserted into the bacterial DNA (the circle DNA)\n\nThen we would re-insert this DNA back into the bacterial host (that the circle DNA first came out of) in a process called "transformation", this is where the broth from the water bath we just discussed is grown in a growth medium at 37 deg. celsius so that the bacteria can grow and produce MORE of those circle plasmids with our foreign DNA inserted into it. \n\nThen we would "plate" these onto agar plates, and let them grow in incubators at 37 deg. Celsius over night until we get small colonies of bacteria on the plate. \n\nEach "mound" of bacteria (small like white dots on the plate) contains millions of copies of our gene (inserted in the circular plasmid DNA of the bacteria). \n\nNow we can take these small colonies, and harvest them further, by putting them in large Erlenmeyer flasks to be grown in the same "growth broth" over night on a shaker for 37 deg. celsius. \n\nAfter of which we can harvest, and purify that culture so that only the circular plasmids remain (this is a long and convuluted process so we won't go into it in detail here), and from there you can store those in a 4 deg. Celsius fridge and keep it in stock for further research purposes. \n\nHope that helps!

Well unless they have invented time machines, and you can go back and get your parents to f_u_c_k on another night, your stuck with your age. As far as the other one, once you turn 18 you can change it.

It can be linked to a specific person because of the DNA \nin it.

change your genetics....ie, you can't. Its like asking how to fight shortness. \nBut, you CAN replace hair...doing the plug thing. But otherwise...diet, exercise, etc...nope.

i am sure u can do this :))) surgically, of course. but i am not sure a doctor will replace and the genitals. it is impossible, as i know. i am student in medicine, your phenomenon is known as transexualism. enjoying to wear female clothes and to change your comportament into a female one. you can try satisfy your need by transforming your exterior in one wich seems like a girl, but anyway, muscles, hair and voice will folow forever your identity.

1) You can't change a past event, that's nescessary for you to be able to change that past event. (You can't kill your distant ancestor)\n2) You can't go experience a future event, that requires someone from that future event to change your present event. (In the 'Planet of the Apes' movie series, Caesar went back to his past, and started an ape rebelion that built the world that Charleton Heston visited when he went into his future)\n\nBut how would you know? Changing the past or the future might create a tangent universe, that we can't experience.

With todays DNA testing the answer must be Yes !\n\nAnd when it comes back of course you can ... everyone needs a hobby.

Sure it WOULD work if there were means to deliver it to each cell, ensure 100% restriction efficiency & specificity, and ligate the DNA nick afterwards. So far it is sci-fi; prenatal diagnostics is the way to go for now.

It's not possible physically. But, what is reality? it's whatever your mind see it as. It's more practical to take some drug and live in some hallucination, of a different reality, than to really go back physically to change the reality.\n\nWhy do u want to goto the past or future? do u want to change something in your favour? Your action would probably triggers a series of event that would again change what u tried to change, or if someone else does not like how u changed thing, they'd simply go back and change things again if time travel is at all possible. These people who does not have a time machine would eventually have one given infinite time to learn to make one and if time travelling is possible, they do indeed have infinite time. In the end, u would not be able to tell the outcome.\n\n\nThe easiest and laziest way to get a time machine is to give yourself one. Once u r done using it, travel back into time to your past and give yourself the time machine... which u got from yourself in the "past".

The drugs won't actually change your DNA but the cells/fluids which are sampled may contain the drug/metabolites. I don't think it is routine for DNA samples to be tested for drugs.
