Dear Sam,
This is a very good and intelligent question.
Yes, you will be passing on your DNA to the other person.
There are four major types of blood cells: red blood cells, platelets, lymphocytes, and phagocyte cells.
White cells, unlike red cells (the RBCs in humans loose their nucleus- but there is something known as the mitochondrial DNA which is passed from mother to child in every generation so that means that u and i have EVE's DNA in us), are nucleated (hence having your DNA) and independently mobile. Highly differentiated for their specialized functions, they do not undergo mitosis (ordinary cell division) in the bloodstream, but some retain the capability of cell division. As a group they are involved in the body's defense mechanisms and reparative activity.
Platelets are formed when cytoplasmic fragments of megakaryocytes, which are very large cells in the bone marrow, pinch off into the circulation as they age. The platelet is metabolically more active than the red blood cell and has a variety of functions. Platelets play an important and not fully understood role in the formation of the blood clot by coagulating to occlude a cut blood vessel and provide a surface on which strands of fibrin form an organized clot, by contracting to pull the fibrin strands together to make the clot firm and permanent, and, perhaps most important, by providing or mediating a series of coagulation factors necessary to the formation of the clot. Platelets also store and transport several chemicals, including serotonin, epinephrine, and histamine (the importance of which in this capacity is unknown), and they phagocytose (absorb) foreign bodies, including viruses, as well. THESE TOO HAVE YOUR ACTIVE NUCLEUS HENCE DNA.
yes you are passing on ur dna to the person.
Very good question indeed... i hope i have satisfied your curiosity.

They will for a period of time. Whole blood can be processed into red cells, platelets, plasma, and cryoprecipitate, or be given as a whole blood transfusion. All of these, with the exception of red blood cell transfusions, will transfer your DNA to someone else for a brief period of time, until the white blood cells in the donor blood have been exhausted ( this time ranges from a few days to a few weeks) or destroyed by their immune system as being "foreign". Red blood cells do not carry dna, only white ones do. A platelet transfusion will result in your mitochondrial DNA being transfered, but not your genomic DNA, again not for very long though.

Red blood cells have no DNA. But if they are getting whole blood, that would include everything: RBC, White blood cells and plasma. If they got your DNA, their immune system would destroy it with no problem. So all those donated cells don't last long in another's system...just long enough to get them through their crisis.

Not really. The person who receives the blood you donated might have crucial matching bits of DNA, but that's about it. The main exception would be if the person you donate to is a family member.

No, they just get your red blood cells (which do not contain DNA) and connective tissue.

yes........and the person that received the blood donation will have to take medication cuz their white blood cells will try and destroy the donated blood
