No. The important parts of blood involved in transfusion are platelets, plasma and corpuscles (red blood cells). None of these contain DNA so its that simple. White blood cells are removed by filtration (Leukoreduction) and as this is the only bit with DNA in it, there's no chance of problems.

No, it doesn't change your 'original DNA' ... although that is a very 'good question' because it means that you are 'thinking' about 'all the stuff DNA can tell us about ourselves' and are wondering if it could 'change it' ... but quite simply, 'blood', while it is a good thing to test for 'DNA' is just a 'simple liquid' and the relatively 'minute' amount you could get from a 'blood transfusion' (approximately one pint ... even if you get more than one pint during the transfusion, each separate pint probably comes from a different donor than any others) and your own DNA is in 'much more' than just your blood. I can't tell you WHY a very short time after the transfusion ALL of your blood would have the same DNA that you were 'born with' ... but I do know that it does.

only for the time the blood is in your system as you do get some white cells along with the red, and that will be a max of 90 days. but it will only change the DNA of the blood, which is why most DNA tests are done by swab from the inside of the cheek.

No. The origional human blood contains an anti body that recognises the foriegn DNA and attacks it before any thing happens. To introduce a domination of the new DNA from the transfusion blood, you would have to rid the person COMPLETELY of origional DNA first, and thats impossible.

No, the transfused blood just mixes with your own and is eventually replaced by your own blood. Plus red blood cells contain no DNA as they have no nucleus.

You will not change your DNA, but you will develop some antibodies to the donor's tissue type. This means that if you have had several blood transfusions in your life and then go on to need an organ transplant, you will have more antibodies in your blood and will need more anti-rejection therapy to combat them and accept the transplanted organ.

no.
blood transfusions add a new "DNA" to your blood stream. eventually your body will kill off all of the new blood cells because it sees it as an invading pathogen. so technically, the new blood doesn't stay in your system long enough to produce new DNA.

No, the donor's blood cells' DNA is eventually destroyed by antibodies. The person's own DNA in the cells remains predominant.

NO, BECAUSE BLOOD CELLS, (WHITE AND RED), DO NOT CONTAIN A NUCLEUS, WHICH TELLS THE CELL WHAT TO DO ETC, WHICH WILL NOT CONTAIN DNA EITHER, THEREFORE WILL NOT CHANGE. THE ROLE OF YOUR BLOOD CELLS, IS ONLY TO TRANSPORT OXYGEN AROUND THE BODY, HENCE WHY TRANSFUSIONS TAKE PLACE - AS THE LOST BLOOD WILL NEED TO BE REPLACED WHEN THERE IS A DRASTIC LOSS.

Uh, no.
There might be some cells left in the tranfused blood which contain the donor's DNA (red blood cells don't have nuclei, but white do) but no, barring some sort of virus messing with some of your cells and giving you cancer, no, you keep your old genes.

Definitely not, your body will accept the blood as being your own as long as it is the same blood type and won't interfere with your DNA
