When blood is donated, is the donor's DNA transferred to the recipient?
2 Answers
Donor DNA can be present, but transiently present and in minute amounts.
Explanation:
Red blood cells and blood plasma do not contain DNA. Red blood cells don't have the DNA containing nucleus and mitochondria. Only white blood cells in blood contain DNA.
With blood donation, usually most of the white blood cells are filtered out. The few white blood cells that might remain thus contain DNA of the donor, but these cells have a short life span and will be eliminated from the body. The presence of these cells with different DNA will not alter the DNA of the recipient.
Sometimes transfusions with 'whole blood' is required in which more white blood cells are transfused. In this case it takes more time before the transfused DNA left the body. Research has shown that it does not affect DNA tests, because the amount of DNA of the recipient is much higher than that of the donor, even in large transfusions.
There will be no effect on genome of the individual after accepting same blood group with different DNA
Explanation:
Transmission of genome is through sex cells. That is through sperm and egg. When you donate blood DNA from blood cells do not enter sex cells. Blood group is the expression of blood group genes.
