ABO blood group system, classification of human blood as determined by the presence or absence of A and B antigens on red blood cells.
Group AB has A and B antigens but neither A nor B antibodies. Group O doesn’t have A or B antigens but has both A and B antibodies. The third kind of antigen is called the Rh factor. You either have this antigen (meaning your blood type is “Rh+” or “positive”), or you ...
red blood cells of humans. If antigen A is present the blood type will be A, and if the blood type is B, then the blood type is B. If both A and B antigen are absent the blood type will be AB. The blood type with O blood type in this both A and B antigens will be absent...
How can type O blood, which has anti-A antibodies and anti-B antibodies, not attack Type A, Type B, or Type AB blood, when they all have the antigens for said antibodies in Type O blood? Wouldn't the antibodies attack the respective antigens in the diffe ...
These antigens are found with type A, B and AB blood but not with type O. More than twenty-five years ago, scientists found that the antigens could be removed to create what they called universal-type cells. They could be removed with chemicals called enzymes(酶). But large amounts of...

Type O is the kind of blood thathospitals most often need. What the researchers are testing is aneasier way to make type O blood out of other kinds of blood.及全文内容可知,文章主要介绍科学家发现了一种制造0型血的新方法。故选C项。
Type AB:The genotype is AB. The antigens on the blood cell are A and B. There are no A or B antibodies in the blood plasma. Type O:The genotype is OO. There are no A or B antigens on the blood cell. The antibodies in the blood plasma are A and B. ...
Red blood cell antigens play critical roles in blood transfusion since donor incompatibilities can be lethal. Recipients with the rare total deficiency in H antigen, the Oh Bombay phenotype, can only be transfused with group Oh blood to avoid serious tra
e. No antibodies Blood Type: Blood type is a classification of blood based on the presence of certain antigens on the red blood cell. The blood types are A, B, AB and O. The Rh or Rhesus factor ...
