Yes
No. You might be thinking of a treatment for sickle-cell anemia, in which a sibling's bone marrow cells are transplanted into a sickle-cell person, and the donor cells take up permanent residence in the recipient's body. But this is a very different thing. A person's DNA is complete in each and every cell of their body. Nothing changes a person's DNA. Ever. Not possible.
Red blood cells lack a nucleus so they don't have chromosones, however they do have mitochondrial DNA from the donor. http://www.answers.com/topic/erythrocyte
Transfer - to convey or remove from one place, person, etc., to another. Transfusion - the direct transferring of blood, plasma, or the like into a blood vessel. Transmission - the act or process of transmitting.
it is rare, but yes. however, blood poisoning is possible and the child could have to have a full blood transfusion if the mother doesn't take pills that the doctor prescribes for the mother if they realize that something is wrong. no, your blood type is in your DNA, and that comes from both parents only, each child gets 50% DNA from each parent.
from my knowledge, it can be used in DNA testing in order to identify a suspect, it can be used to trace a person using this DNA, and can provide hard edvidence showing that someone was at the place of the blood, unless someone just had their transfusion lol, it can be used to do some other stuff but those are the main bits, in my opinion.
Nuclear transfer
Nuclear transfer
the importance of DNA transcrition is it will help DNA transfer where it needs.
DNA technology will transfer bacteria genes from cell to cell.
Genetics engineering is needed to transfer genes through DNA molecules.
You can have a blood test done, but believe it or not the technology is gearing more towards the swab and the swab is as accurate. One of the reasons is the fact that sometimes people might have a blood transfusion or bone marrow transplant which can jeorpadize the test result.
