Agee Ms. Songer AP Biology February 16 2015 Sickle Cell Anemia: Case Study Summary Sickle Cell Anemia is a painful diseases that is caused by a mutation in the protein called hemoglobin which helps carry oxygen in red blood cells. Because of the mutation‚ the hemoglobin is shaped oddly which results in pain because it is hard for the blood to travel throughout the body and anemia because of the lack of oxygen in the blood. A person can only have this disease if both parents are carriers and they receive

‘How could natural selection increase the number of children born with sickle-cell disease in certain regions when these individuals are unlikely to survive and produce offspring?’ Darwin’s theory proposes that 3 conditions are a requisite for natural selection to occur. They are a struggle for existence of the offspring as they are competing for limited resources‚ variation within species which gives some individuals advantage over others hence better chance of survival and lastly inheritance

TREATMENT OPTIONS There is NO cure for sickle cell disease‚ although new stem cell research is promising. Bone marrow transplant is a potential cure‚ however finding a matched sibling donor is difficult. Therefore treatment is primarily focused on management of symptoms and prevention of pain episodes. Hydroxyurea (a chemotherapeutic medication) is the only recognized treatment option for the prevention of vaso-occlusive crisis in SCD. It is a prescribed drug for adult patients

having sickle cell anemia can make a person more resistant to contracting malaria If it had not been for Anthony Allison‚ the world as we know it today would drastically change. Like the video stated‚ many people with the sickle cell anemia would meet “death before adulthood”. Areas with high frequencies of anopheles mosquito and sickle cell anemia would correlate but nobody would understand why. I admire Allison for not only having the burning inquiry to determine why the sickle cell anemia character

Sickle Cell Anemia Sickle Cell Anemia is a blood disorder that shortens the life span of red blood cells‚ and eventually the organisms they are located in. Sickle Cell Anemia is an inherited blood disorder that changes that structure of red blood cells. In a healthy organism‚ red blood cells are disk shaped and move easily through the blood vessels. In an organism that has sickle cell anemia the red blood cells’ structures are corrupted; instead of the disk-like shape‚ the red blood cells have

Sickle cell anemia is an inherited blood disorder that cause the abnormal formation of the hemoglobin protein in red blood cells (Nih). Hemoglobin is an essential protein that resides within the red blood cells supplying oxygen to the entire body. Hemoglobin S causes a mutation in shape of hemoglobin protein causing a group of blood disorders including sickle cell anemia and thalassemia. Sickle cell anemia is a result of one abnormal hemoglobin S gene given to a child by each parent‚ children that

Anemia is a condition in which there is lower than normal number of red blood cells or hemoglobin within a person‚ consequently decreasing the amount of oxygen being carried to the rest of the body. Causes of such a condition are usually insufficient amounts of iron‚ blood loss‚ lack of red blood cell production‚ or high rates of red blood cell destruction. (MNT‚ http://www.medicalnewstoday.com/articles/158800.php) One form of this condition is the disease Sickle Cell Anemia‚ an inherited blood disorder

Sickle cell anemia (SCA) is a genetic disorder that is hereditary. It affects the blood‚ and is caused when the hemoglobin in blood cells are deprived in oxygen from the proteins. These cause normal round blood cells‚ to have are rigid sickle shape. People affected by SCA have a higher risk of death‚ stroke‚ severe attacks‚ and severe rushes of pain. James Herrick discovered an anemia‚ and found bizarre sickle-shaped cells in 1910. A treatment for the disease was discovered in the 1920s by E. Vernon

Sickle Cell anemia is a group of inherited red blood cell disorders‚ or a collection of recessive genetic disorders characterized by a hemoglobin variant called Hb S. 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‚

Genetics- Word Count: 214 Sickle cell disease is a genetic blood disorder that plagues millions of people all over the world‚ the highest concentration is found among people of Sub-Saharan African descent. Sickle cell disease is caused by a mutation in the HBB gene located on chromosome 11. Hemoglobin in red blood cells is how oxygen is delivered to cells throughout the body and is composed of four subunits‚ two subunits of alpha- globin and two of beta- globin. The HBB gene provides the instructions
