There will be DNA in the blood you get but those cells don't divide so after they get old and die the foreign DNA will also disappear. In your blood you can find DNA in the white cells, the red cells don't have it because they don't have a nucleus.

When you receive a transfusion of whole blood, a fraction of the cells that are present, the lymphocytes (white blood cells) carry the DNA of the donor (there are some other cells as well, but they are such a minor fraction that it is essentially unimportant). So for as long as these cells are in your circulation you will have "some small amount of someone else's DNA" in your peripheral blood. As these cells die and are cleared by the body, you will eventually no longer have any cells with the donor's DNA genotype. For the other person who wrote it, erythrocytes (red blood cells) have no nucleus and NO DNA.

Certainly, but the blood's crossmatched before transfusion to limit the risk of your body's mounting a major immune response to the "foreign substance," and it's not like it lasts forever, anyway. Also, your chances of having a whole blood transfusion these days are pretty remote. Component transfusions (RBC's, platelets, whatever) are the norm. The DNA load in various components varies somewhat.

DNA means deoxyribonucleic acid and is a main component of genes and chromosomes. It is the genetic material in the nuclei of cells. DNA has the code that controls the activities of a cell. Short sections of the code control the production of cell enzymes, which regulate the chemical changes involved in cell activities such as respiration. DNA also has the ability to make a copy of itself. One chromosome is said to be made up of one very long DNA molecule with molecules of protein attached along its length.
Since blood also carries protein tissues, it is quite safe to conclude that there are also DNA molecules attached to them, DNA being building blocks that are arranged in the shape of a double helix, joined together by bonds, making it appear like a spiral ladder. It is estimated that all the DNA in a typical cell adds up to more than one meter long.
So, the answer is yes. -- Graciana

Surely. Every cell contains DNA red cells also
So, you are sure to receive DNA but it is not harmful since there would be no transfusion

No you would still have your own DNA. Your DNA does not change from a blood transfusion or blood given during surgery etc...

Well, the DNA of that blood would be in your system, but since it can't match up with yours--you know, how it splits & reconnects to another half of a "ladder"--it can't replicate, so you don't turn into who ever's blood you recieved. ( I hope that came out like it was in my head.)

DNA is usually tested by swabbing the mouth so whatever was in your blood would not affect your saliva or cheek cells
