when one undergone blood transfusion, does his/her DNA fused to the donor's DNA?

Answer 1

No--there will not be any transfer of DNA...for a couple reasons.

First, blood is primarily red blood cells which have no nuclear DNA in them. They are little more that sacs of hemoglobin. So, the only DNA in a blood transfusion is from the white blood cells.

White blood cells in your blood stream do not divide and reproduce--special cells in your bone marrow make them.

So, when you receive a blood transfusion you do have a stranger's DNA floating around in your blood stream for a while, but it's not "active" DNA and it gets broken down and recycled like any other molecule.

Interesting question.

Answer 2

No, the DNA isn't incorporated into the person's body. The transfused cells are present to help them live during the period when they need some extras, but then the cells die and are disposed of on the normal time-scale (for erythrocytes -- "red blood cells" that is about 120 days).

In some types of bone marrow transplants, the cells that make blood components are introduced into the recipient and they are incorporated into the bone marrow permanently. Those cells live along-side the recipients own... making the person a "chimera" with tissues from two genetic sources. But even then, the DNA does not combine.

Answer 3

No way... just the blood cells of the donor run along with the patients blood cells. They must be of the same blood type, because if not, T cells will recognize estrange blood cells as antigens attacking them

Answer 4

No, the blood is eventually processed out of your body as all blood is as it wears out and your body makes more.

Answer 5

no
your body just wants those little red ones
called cells
our body just loves to eat them up and make new ones to.
that's why the blood is needed mostly.
