Can one alter his or hers DNA over time?

DNA can be altered in the short term through damaging substances such as all forms of radation....including tanning beds...chemicals, etc.   These types of changes usually lead to cancer and is probably very close to impossible to lead to a good change (although the change would only be for one cell that would probably not be passed on).  The other way is through evolution, which is obviously the long term.

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.

Neither.  DNA doesn't change.  And the heart only pumps the blood, it doesn't make or act on it.

it is in their DNA which becomes differentiated and diffuse through age...

There have been massive improvements in DNA testing in the last 11 years, a retest could be done....;

At this point in time it isn't really possible.  in theory it is though.  we can manipulate chromosomes in bacteria and viruses and engineer plants to contain more vitamins or be bacteria resistant but humans are different.  tampering with humans brings up a whole array of ethical questions.  If we were to 'engineer' humans to be faster, smarter and such we would have to select for those traits we want from people who possess these qualities and 'insert' that trait into the chromosome of the subject.  in theory we could do much more with this technology.  Currently this technology is a near vision at best.  \n\n~Chris~

Ultimately all changes in DNA sequence across all living organisms are the result of mutations.  Essentially, the copying process went wrong somewhere along the line and generated a change.  These may occur as a result of many factors.\n\n1.) Substitutions are changes in single bases.  A becomes T for example.  In a large fraction of cases, this will lead to  a change in the amino acid, which in turn changes the protein.\n\n2.) Indels (insertion/deletion events) will add or subtract DNA.  During replication, a segment of DNA may be added or removed leading to a change.  It is also possible that DNA becomes damaged or lost and that change is passed on to future generations.\n\n3.) Recombination can lead to novel arrangements of existing strands of DNA.  It can also occur improperly and generate change (often through indels).\n\n4.) Chromosomal rearrangement.  If chromosomes break they may reattach elsewhere, become a whole new chromosome, or lose parts entirely.  This can lead to moving an allele into a completely new gene environment.  The protein itself may not change, but the expression of the protein might.\n\nFinally, natural selection and random effects (such as bottlenecks) will affect the gene frequencies.  Sometimes these will allow for new interactions of genes.

No.\n\nMilk does not have cells, so it can't be "genetically altered." Some of the cows that make it have been genetically modified, but no scientist has ever been able to demonstrate a difference between the milk from GE cows vs. "normal" cows.

If it is possible (and that's a HUGE "if"), there would have to be some kind of rule to the effect of "you cannot allow your actions in the past to affect the future."\nThere was an episode of the old "Twilight Zone" TV show that touched on that very topic.

Many times what happens is a specific gene or stretch of DNA is duplicated in an organism.  If this doesn't cause any harm, one copy of the gene can mutate, leaving the other one intact to carry out its original function.  The extra gene can then become something entirely different over time, occasionally mutating into something useful.  \nA word of warning- don't start with a belief and look for the evidence.  You will find evidence (not good or true evidence, but you will find something) for whatever you go out looking for, especially on the internet.  Find the evidence first and see where it leads you, or you will end up very, very wrong about some important things.

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

An existing organism is born with certain genes.  Those genes determine how that organism will develop during its life.  Those genes cannot change ... there is no mechanism in life to alter the genes for the entire organism (individual cells yes ... e.g. cancer, but not the entire organism).\n\nSo even if that single organism lived for centuries (like a redwood tree), it cannot change (evolve) in ways not dictated by its genes.\n\nNew life (offspring) is a brand new set of genes ... a new mixture from each of its parents.  \n\nSo each offspring can be different from either one of its parents ... better or worse in some characteristics, or all characteristics, from either parent.\n\nSo over the entire group of individuals in a species ... you have many individuals with slight improvements over their parents.  Those will produce more offspring than those who have fewer improvements (or are slightly worse adapted) than their parents.\n\nThe result is evolution.  Many many tiny improvements in genes, over many many generations.  You cannot have that evolution, without the opportunity for new genes with every new life.

cloning only can happen by taking dna from say one person the clone then has the same dna identical twins may have all of the same looks as a cloned person would but has differnt dna

When thereis a mutation in the body cell. I COULD be past on. it's not a 100% chance. but it's possible. \ncan you give me the 10 points since i'm the only one who answered it .
