they are blood types
Blood type O lacks the antigen proteins of A and B. Blood type O is the universal donor.
Iron, vitamin B 12 and B vitamin folic acid produce red blood cells
Blood alleles are the genes that determine what kinds of proteins will be present on the surface of red blood cells, which are called antigens. These alleles determine blood type - A, B, AB or O. There are actually only two proteins that are present in human blood, A and B. Type O blood is an absence of either A or B proteins. Therefore, blood type is determined by the genes you inherit from your parents. All humans carry two alleles. For example, one person may have one allele for A type blood and another allele for no protein (O type). This person will have type A blood. Another person may have one allele for B type blood and another allele for no protein (type O blood) and would be classified as having type B blood. If these two people were to have children together, they would be able to produce children with all four blood types. This is because each parent would contribute one allele to the child. If the child received the A from parent 1 and the B from parent 2, the child would have type AB blood - both the A and the B proteins present on the child's red blood cells. If the child received the A from parent 1 and the O from parent 2, the child would have type A blood. If the child received the O from parent 1 and the B from parent 2, the child would have type B blood. If the child received the O from parent 1 and the O from parent 2, the child would have type O blood - no proteins present on the child's red blood cells.
To type blood according to abo, the lab detects the proteins of the cells to determine whether blood is a b or o. To further type blood into rh- and rh positive, the lab checks antibodies to specific proteins.
red blood cells. These surface proteins determine an individual's blood type by reacting with antibodies in the blood. The most well-known blood group system is the ABO system, which classifies blood into types A, B, AB, and O based on the presence or absence of certain antigens.
O blood has no major proteins that A and B blood have. For example: If someone had B blood with its specific proteins, this person cant receive A blood because it has the specific A blood proteins that will cause bad clotting to stop it. O blood (with no different proteins) wont affect any blood.
Each blood type has it's identifying proteins, and will reject blood with the wrong proteins. Type A blood is anti-B, type B blood is anti-A, type O blood has both, and type AB blood has neither. Imagine if someone with AB blood tried to donate to someone with A. AB blood has identifying proteins A and B. The type A blood would recognize the B proteins and kill the cells. The same thing would happen with B, which would recognize the A proteins and kill the cells. Type O blood would recognize and reject both the A and B proteins and reject them. However, if someone who is type AB gives to AB people, their blood does not destroy neither protein A nor B, so it would accept it.
Blood type O lacks the antigen proteins of A and B. Blood type O is the universal donor.
blood type A
A blood group or blood type is based on the presence or absence of two proteins (A, B) on the surface of red blood cells. Because two proteins are involved, there are four possible combinations or blood types (ABO groups):Type A - Only the A protein is present.Type B - Only the B protein is present.Type AB - Both proteins are present.Type O - Neither protein is present (about 40 percent of the population).
No, the only difference is in the shape of certain proteins.
blood type A
Different proteins cause different blood types. A and B are two different proteins, as is M and N. O is the absence.
blood type A
Blood types are determined by the presence of specific proteins (antigens) located on the surface of red blood cells. These proteins include A, B, and Rh (D) antigens.
A person's blood type depends on the presence or absence of certain proteins called antigens on the surface of red blood cells. These antigens determine whether a person's blood type is A, B, AB, or O.
B. the formation of blood clots :)) By simone :) Hi rubyy!
