Blood Transfusion?

Question

I was just wondering. If a person recieves a blood transfusion, will the donor's DNA be in the reciepient for life or will cell turnover kill it??

Answer 1

Cell death will eventually get rid of all extraneous DNA evidence.

The DNA is only in the cells transfused.  The DNA does not "transfer" into other cells.

Answer 2

blood transfusion causes transfer of blood from doner to recipient. now blood cell do not've nucleus so no DNA. n fpr extravenous DNA them its digested by lysosomal enzymes. n thus no DNA of doner can transfer from doner to recipient

Answer 3

I know people who have have had blood transfusions... Donors DNA does not enter the recipients body--the cell turnover kills any likelihood of that...

Answer 4

The DNA will last in the recipient's body for as long as the donor cells do, and that isn't long (a matter of weeks). That is the simple answer.  Several years ago, however, in a study done in the USSR, perfused cells from an animal were found in the human recipient years after the transfer.  But that was the USSR, so who knows?

But for all intensive purposes, the donated DNA will disappear pretty quickly.

Answer 5

All your red cells turn over in about 4 months. So, the donor cells (and their DNA) would also be destroyed in that process.

White blood cells last a matter of days.
