Every cells of (molecular )biology has its own existence of it.Is there anyone except got which you asked so if get then say otherwise which I have told that is true.
Hello Nouman Shahzad
The blood group "O" does not have A or B antigens on the surface of its red blood cells. So, during blood transfusion, when a person with blood group "A" receives blood from the person with blood group "O", even though the plasma of blood group "O" contains antibodies for antigen A, agglutination or coagulation does not occur because the antibodies in the "O" blood group do not react with A antigens present in blood group "A" as they do not recognize them as foreign.
On the other hand, the blood groups "A" and "B" contain antigens A and B respectively. These antigens present in A and B blood groups can recognize antibodies present in blood group "O" and can result in blood transfusion reaction. So, the person with blood group "O" cannot take blood from blood group "A" and blood group "B".
Thus, blood group "O" is called a universal donor but cannot accept any blood group other than type "O".
Best.
