2. . Sickle Cell Anemia Affects the B-chain of Hemoglobin. It is a genetically inherited disease, and is seen commonly in Africa. Sickle Cell Disease is a group of inherited red blood cell disorders. Normal red blood cells are round like doughnuts, and they move through small blood tubes in the body to deliver oxygen. Sickle red blood cells become hard, sticky and shaped like sickles used to cut wheat. When these hard and pointed red cells go through the small blood tube, they clog the flow and break apart. This can cause pain, damage and a low blood count, or anemia. Sickle Cell Normal Cell

9. Cystic fibrosis (CF) is a life-threatening genetic disease affecting approximately 30,000 people in the United States. For people with the disease, a defective gene causes the body to produce a faulty protein that leads to abnormally thick, sticky mucus that clogs the lungs and can result in fatal lung infections. The mucus also obstructs the pancreas, causing difficulty for a person to absorb nutrients in food and can block the bile duct in the liver, eventually causing permanent damage in approximately six percent of people with CF. What is CF?
