No... During a blood transfusion, you are getting RBC (Red Blood Cells).. among many mammals, mature RBC lack a nucli, which houses DNA--- Humans are among these mammals--- only your WBCs contain DNA.
The theory is that RBC evolved among mammals to give up their nucleus so that they can store other important molecules that are transported through the blood.
Edit:
To correct what someone below me stated: RBC live for 120 days... and WBCs only live for 3 days-- so even if you got some WBCs during a blood transfusion, they would die w/in 3 days of the transfusion.

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... blood does not change your DNA this is because the blood does not contain any natural viruses that have the ability to do this however if for example there is a cirus like HIV in the blood, the humman difiency virus (HIV) will attack the ther white blood cells (WBC) and cause a mutation in the blood..but the total DNA structure is virtually unchangeable.

No! It would be possible if your blood cells divided by themselves that one day the other person's blood cells would rival you own inside your body. But... it's actually your bone marrow that produces red blood cells, and your bone marrow is making them from your own DNA, so once the transfusion cells die, they are gone forever. This is why people with sickle cell or other blood cell diseases can't be cured by just draining a large quantity of blood and replacing it with a healthy person's.

No but incredibly heart transplants have been found to affect deep seated desires. A neural network has recently been found w/in the heart that may explain why tastes and desires can change radically after transplantation!

No - red blood cells do not in fact have DNA (their precursors do - the reticulocytes).
Someone elses red blood cells will not change your DNA

No. Your DNA is your genetic fingerprint and is therefore totally unique to you.

Yes and within a week you'll look exactly like the person whose blood you received...
lol - don't be silly!

Hey you will never be the same, are you the only one who has not heard of the farc called 'stem cells'? the dude gives his with his 'stupid' blood, and it lives with you till you return to mother ashes.
(Hey don't quote me! else my boss will kill me and I will never tell you anymore of the stuff you were never meant to know).
