the answer is no. recipient' dna does not mutate.
these people how are saying that rbc does not contain dna are right HOWEVER, they are also WRONG. because in a regular blood transfusion we transfuse packed cells which also contains wbcs which has the donor's dna. there is a so called leuko-free packed cells meaning free of wbc but still these is not totally free of wbc contains 1-3%wbc. these used of blood product is very rare and only use twice in my entire career.
rbc's life span is approx 120 days meaning the transfused cells by this time we hope that the patient is already producing his own rbcs.

Blood has 4 elements: the RBC's, WBC's, platelet, and plasma. WBC 's do contain DNA. However most blood transfusions involve only RBC's ( packed cells), which do not contain DNA. Blood ,even in rare Whole Blood transfusions, no traces of foreign DA from the WBC have been detected in a recipient's blood.
On the other hand, there is at leat one situation in which a transplant can change your DNA. After a bone marrow transplant, the DNA in a blood sample may actually reflect the donor rather than the recipient. That's because, in this case, blood stem cells are transferred. The recipient will produce blood that contains the donor's cellular elementsbut alsmost none of his or her own DNA.
And yes, this could affect DNA blood evidence. Though, there are other ways to test for DNA e.g. body fluids such as semen., epithelial cells,etc. Then there's a the ever rarer cases of blood being transferrred due to the anti-social behavior of vampires. But that's a whole other ball of serum.

No, the person's DNA can't change. The other DNA will just be present, but it won't do anything unless the transfusion went wrong and the bloodtype was different. DNA can't mutate after it is formed from the very first two cells that made it in a zygote (egg and sperm). The only thing after that first gene splicing, any other mutations are due to radioactivity or something major (cancer cells are mutated cells)

No, red blood cells contain no nucleus. Therefor, there can't be any DNA present. Also, simply the presence of DNA will not induce mutation in the DNA of the recipient.

No. There is no DNA in erythrocytes (blood cells). The donated red blood cells live out their lives (about 120 days) and disappear... hopefully by then the recipient's body is making enough on their own to survive.

no, there is no DNA in the red blood cells. secondly, cells only mutate will expose to certain stimulates e.g. X-rays, UV rays. For a DNA to mutate into another DNA, you will need to use a virus to tranform the cells.

No, there's no DNA in a red blood cell.

no the dna doenst mutate. Blood cells dont copy themselfs, so they just live their life and die.

No, it does not mutate until it is culled in the spleen after its usual life span.

NO. your immune system just can't tell that its not your blood.
