Chromosome 11 Research Paper
Chromosome 11 is in group C, it is of medium size, its relative length is 4.82 Chromosome 11 is submetacentric, meaning that the centromere is closer to one end, causing one longer arm and one shorter arm. The centromeric index for chromosome 11 is 40.46. Calculations can be seen below.
Centromeric index = (p / p + q) x 100
(1.95 / 4.82) x 100 = 40.46
The protein that HBB gene encodes is beta-globin. Beta-globin is a component of hemoglobin. Hemoglobin is found in red blood cells, and it normally consists of four protein subunits. Beta-globin can be found in two of these subunits. The two beta-globin subunits attach to heme, a molecule containing iron. This iron molecule in the center of heme can bind to one oxygen molecule. This allows hemoglobin

Sickle cell disease is caused when there is a mutation on the HBB gene. This mutation produces hemoglobin S (HbS), which is an abnormal version of beta-globin. People with sickle cell disease have at least one beta-globin replaced with hemoglobin S. This causes red blood cells to become misshapen or sickle, meaning that the red blood cells are breaking down. Symptoms associated with sickle cell disease are anemia, which is when a person has a low number of blood cells, infections, and episodes of pain. Anemia can also cause delayed growth and development in children. Yellowing of skin and eyes may also be seen do to the rapid breakdown of red blood cells. The severity of symptoms can vary person to person. Treatment for sickle cell disease will not cure the patient but medications, blood transfusions, and, very rarely, bone marrow transplant can help with the symptoms.
Sickle cell disease can be found in millions of people around the world. However, it tends to affect people with ancestors from Africa, India, Mediterranean countries, Central America, some parts of South America, and the Caribbean. In the US “sickle cell disease is the most common inherited blood disorder… affecting 70,000 to 80,000 Americans” (Sickle

    The mutation in sickle cell imitates one change in the amino acid building blocks of hemoglobin, which is the oxygen-transport protein. Hemoglobin is the component that gives red cells their color and it has two subunits, the alpha and the beta. The alpha subunit is normal in people with sickle cell disease. The beta subunit is the issue. It has the amino acid valine at position 6 instead of the glutamic acid that is normally present in that position. More valine causes the DNA to be larger and probably heavier too. This positioning is the very alteration that is the basis of all the problems that occur in people with sickle cell disease.…

    Sickle cell anemia affects people with African, Mediterranean, Middle Eastern, and Indian ancestry (Scientific American). Sickle cell anemia occurs when a person inherits two sickle cell gene, one from each parent, that cause the red blood cells to change and become crescent shaped. The underlying problem involves hemoglobin, a component of the red blood cells. Hemoglobin is a protein molecule in red blood cells that carries oxygen from the lungs to the body’s tissues and returns carbon dioxide from the tissues to the lung. In sickle cell anemia, the hemoglobin is flawed (The New York Times). As a result, the cells become sickle shaped and can’t travel as easily through blood vessels. Sickle cell anemia is an illness, which has one primary cause, but a variety of symptoms and treatments (Scientific American.) Like some illnesses, sickle cell anemia has one primary cause. In order for sickle cell anemia to occur is when a sickle cell gene have, been inherited from both the mother and the father, so that the child has two sickle cell gene. The sickle cell gene causes the body to make abnormal hemoglobin. As mentioned above, hemoglobin is a protein molecule in red blood cells that carries oxygen from the lungs to the body’s tissues and returns carbon dioxide from the tissues to the lungs. A person with normal red blood cell will have hemoglobin A; however, a person with sickle cell disease will have hemoglobin S…

    Sickle cell anemia is the most common form of sickle cell disease which is an inherited, autosomal recessive disorder that causes an abnormal hemoglobin cell. The person with this specific disorder inherited hemoglobin S from both parents, also known as homozygous (Lewis, Dirksen, Heitkemper, & Bucher, 2014, pp. 644-647). This hemoglobin S results from the substitution of valine for glutamic acid on the B-globin chain of hemoglobin, and this ultimately causes the erythrocyte to stiffen and elongate taking a sickle shape in response to low oxygen levels (Lewis et al., 2014, pp. 644-647). Due to the sickle cells elongated shape, and its stiff and sticky consistency it tends to get stuck in capillaries and vessels, and blocks blood flow to limbs and organs (Lewis et al., 2014, pp. 644-647). The major problems with sickle cell anemia is due to their sickled shape, reduced life expectancy and their ability to carry enough hemoglobin or transport it properly to…

    Sickle cell anemia is a disease where your body produces abnormally shaped red blood cells. The cells are shaped like a crescent or sickle used to cut wheat. As the sickle cell blood cells don't last as long as normal round red blood cells this then leads to anemia. The sickle cells can also get stuck in blood vessels, blocking blood flow and are unable to get oxygen around the body effectively.…

    Sickle cell anemia or also known as sickle cell disease is a hereditary genetic disease defined by the presence of odd shaped crescent-shaped red blood cells instead of the regular round disc like shape cells. Red blood cells transport oxygen from the lungs to various other organs and tissues with the help of a protein called hemoglobin. The main cause of sickle cell disease is when hemoglobin mutates into an abnormal type called hemoglobin S. The presence of Hemoglobin S causes red blood cells to be sickle-shaped and rigid, making it more difficult for them to flow through blood vessels in the body to deliver oxygen. Therefore, the sickled cells latch onto the walls of various blood vessels throughout the body, resulting in blocked blood flow that can lead to organ damage, pain and infections…

    Sickle cell anemia is a disease passed down through families in which red blood cells form an abnormal crescent shape. The “sickling” occurs because of a mutation in the hemoglobin gene. Sickle cells are stiff and sticky. They tend to block blood flow in the blood vessels of the limbs and organs. Blocked blood flow can cause pain, serious infections, and organ damage. Life expectancy in people who have this disease is shortened.…

    Sickle Cell Anemia, also known as Sickle Cell Disease, is a disease that causes the production of abnormal hemoglobin. The red blood cells (RBCs) carry oxygen to organs and tissues. Hemoglobin, a molecule in the RBCs, is a protein that attaches to the oxygen in the lungs and carries it to all parts of the body. Hemoglobin takes on the oxygen, and releases carbon dioxide, a process known as oxygenation. In the tissues, deoxygenation occurs where the processes is reversed, when hemoglobin releases oxygen and takes on carbon dioxide. When the RBCs are healthy, they can easily move through the tiniest blood vessels throughout the body because of their flexibility. The hemoglobin S is fragile and abnormal in Sickle Cell Anemia, and the RBCs are pointy with a shape like the alphabet letter "C" or the crescent moon. This makes the RBCs difficult to move pass through the blood vessels. The RBCs become hard, and can get stuck in blood vessels, and often clog the spleen. This causes pain, infection, and poor blood flow in patients that have Sickle Cell Anemia. The RBCs also block blood flow to organs, such as the heart, lungs, brain, etc., which can lead to stroke, damage to organs, especially the spleen, acute chest syndrome, disability, and sometimes, even death.…

    Sickle cell disease is an autosomal recessive genetic disorder most common in African Americans, which results from a mutation affecting the amino acid sequence of the beta chains of hemoglobin molecules in red blood cells. The abnormal hemoglobin which causes the red blood cells to sickle is called hemoglobin S. Sickling occurs when the red blood cells are deoxygenated causing the cell to have a hard curved crescent shape. Due to their shape the sickle cells can become trapped in blood vessel walls causing a circulatory blockage and could cause tissues to become oxygen deprived, pain, infection, and organ damage. Red blood cells in sickle cell disease also have a life span of 10 to 20 days compared to normal red blood cells of 120 days; because of this shortened life span chronic hemolytic anemia occurs (Thompson, 2012). All together sickle cells disease causes a dramatic decrease in the quality of life that can lead to early death, the absolute need for medical intervention, and transplantations.…

    INTRODUCTION: “Pain” sudden or chronic, lasting from a few hours to a few days; from a few weeks to a few months evolving from an adhesive substance in red blood cells. The “Pain” is inherited by an retriction blood flow through the body do to an abnormality in the cells. “Sickle Cell Anemia” a chronic illness discovered in 1910 by an American physician named James Bryan Herrick. Sickle Cell is more that just pain; it is a disease that is affected by abnormal blood cells that has an adhesive formation causing the natural flow to be compromised. As a result, these abnormal cells become fixed in the blood stream and not flowing to major body organs causing extreme pain and even a stroke. Why is this process painful? Have sickle cell patient become tolerant to pain or is it because some of them handle self-care management? For many years there has been a link between Sickle Cell Anemia and Pain caused by the stickiness of the blood cells. When this occurs, it decreases normal blood flow to the major organs causing strokes.(citation ). Sickle cell anemia is most common in people whose families come from Africa, South or Central America (especially Panama), Caribbean islands, Mediterranean countries (such as Turkey, Greece, and Italy), India, and Saudi Arabia. In the United States, it's estimated that sickle cell anemia affects 70,000–100,000 people, mainly African Americans. The disease occurs in about 1 out of every 500 African American births. Sickle cell anemia also affects Hispanic Americans. The disease occurs in more than 1 out of every 36,000 Hispanic American births (Citation).More than 2 million Americans have sickle cell trait. The condition occurs in about 1 in 12 African Americans. In people with sickle cell disease, approximately 50% do not survive beyond age 20 years, and most people do not live past 50 years of age (Citation)…

    Therefore, provision of optimal care plans and effective treatments for patients with sickle cell anemia must cumulate more research and funding. A large issue with the type of aid offered to sickle cell patients comes from the lack of treatment and medicines that are made available to patients. Painful attacks sickle crisis are things patients with SCD are subject to regularly. Crisis tend to render sickle cell patients immobile for large periods of time with intense sharp pains to the joints muscles and head. A sickle cell crisis occurs because of the accumulation of red blood cells in the blood stream causing a blockage. This block causes restricted flow of blood towards the rest of the body. Studies have shown that because the available treatment for sickle cell is limited and the availability of treatment medications are scarce, the population of people suffering from SCD are left medically neglected, prompting the need for more research and fund allocation towards sickle cell research even more evident. In a study performed by “the National Heart, Lung, and Blood Institute over the effectiveness of Hydroxyurea in treating SCD, showed that there was a noticeable decrease in their attacks, and a 40% reduction in mortality” (Halsey…
