Question details

1. The ABO blood typing system was discovered by Karl Landsteiner in 1901, for which he received the Nobel Prize in Physiology or Medicine. The biochemical basis of ABO blood types is shown in the diagram below The A blood type is because an enzyme adds an acetyl-galactosamine (purple colored) to the sugar backbone on the red blood cell surface. The B blood type is because an enzyme adds a galactose (beige colored) to the sugar backbone on the red blood cell surface. boxes N acetylgalactosamine Fucose Red blood Diagram showing the carbohydrate chains that determine the ABO blood group With respect to genetics, ABO blood types are controlled by a single gene designated I, which has three alleles The r4 allele gives blood type A, /B gives blood type B, and i gives blood type O. The r4 and /B alleles are co- dominant and i allele is recessive to both the and 7 alleles. With this knowledge fill in (white boxes) on the Table below. When filling in the white boxes use the same informational format as the filled in colored boxes.
