The Change Of Hemoglobin Changes Essay - 1210 Words

Homework #9 Chapter 11: 1. The change in hemoglobin changes as the change in the oxygen in the environment occurs. Each globin usually has two polypeptide chains encoded by genes that attract oxygen molecules to different degrees. 2. The pancreas which has two types of cell clusters. A transcription factor is activated and change the expression of a gene in a way that stimulates some progenitor cells to divide. 3. Proteomics is an area where gene expression emerges. It identifies and analyzes all the proteins that made in a cell, organ, or body. 4. The histone protein plays major role in interacting with other chemical groups which expose DNA and shield some sections. 5. Acetyl plays role can start the transcription. Methyl groups binds to a specific amino acid in a specific histone type. When the CH3 are added methylation spreads from the tail of one histone to the adjacent histone. The addition of phosphate is example of epigenetic changes. The addition of these three groups should be balanced. 6. MicroRNA’s can affect the gene expression by preventing their translation onto protein. This blocking function lead to enabling the cells to adapt to change condition. 7. Because the genes in pieces of exons and introns and alternate splicing make it possible for one store of information. 8. By using different information in a gene, the proteins can be resulted. These information is called isoforms where the driving force behind which version of a protein a cell makes isShow MoreRelated Discovering Sicke Cell Anemia Essay1320 Words   |  6 Pagesa protein called hemoglobin which transports oxygen from your lungs to every part of your body. Hemoglobins oxygen carrying ability is essential for living but if there is a structural defect on the pigmented molecule, it can be fatal. When a normal red blood cell distributes its oxygen, it has a disc shape. But when an affected red blood cell containing sickle cell hemoglobin releases its oxygen, the image of the cell changes from a disc shape to a sickled shape. In hemoglobin, there are four chainsRead More Sickle Cell Anemia Essay1282 Words   |  6 Pagesis carried in red blood cells by a substance called hemoglobin(Hemoglobin – is the main substance of the red blood cell. It helps red blood cells carry oxygen from the air in our lungs to all parts of the body). Normal red blood cells contain hemoglobin A. Hemoglobin S and hemoglobin C are abnormal types of hemoglobin.Oxygen is carried in red blood cells by a substance called hemoglobin.The main hemoglobin in normal red blood cells is hemoglobin A. Normal red blood cells are soft and round and canRead MoreFunction and Structure of Hemoglobin and Myoglobin Essay822 Words   |  4 Pagesnoncovalently bound to myoglobin and is essential for the biological activity of the protein. A three-dimensional structure of hemoglobin is determined by X-ray crystallography showed hemoglobin is made up of four polypeptide chains, each of those chains has a very similar three-dimensional structure to the single polypeptide chain in myoglobin. The major type of hemoglobin found in adults (HbA) is made up of two different polypeptide chains: the alpha-chain that consists of 141 amino acids residuesRead MoreThe Alpha Chains1584 Words   |  7 Pagestransported to the red blood cells. This means that oxygen is not being transported to the hemoglobin protein. The hemoglobin protein has to be released from the red blood cells and be released into the plasma by enzymes that contain heme. After the enzyme release the protein, the red blood is destroyed and hemoglobin can release oxygen into the bloodstream. With Alpha Thalassemia, the low functioning numbers of hemoglobin are not enough to provide stable oxygen levels. If the levels are too low anemia isRead MoreThe Probability of Inheriting a Disease Is Not Random1816 Words   |  7 Pagesinherited and it affects the anatomy of the red blood cells, resulting in a sickle shape which then affects the functions of red blood cells causing a blood disorder. Sickle Cell is a recessive disease and persons affected have both copies of the hemoglobin S gene. This genetic defect causes red blood cells to become sickle-shaped (cresent shape). The abnormal shape severely impede the ability of red blood cells to pass through small blood vessels. This impediment caused by the sickle-shaped red bloodRead MoreThe Theory Of The Equilibrium System1086 Words   |  5 Pagesthat were studied in this experiment were changes in the temperature of the system and changes in concentrations of reactants or products. Le Chatelier s Principle states that when an equilibrium system is subject to a stress, the system responds by attaining a new equilibrium condition that minimizes the imposed stress. The main stresses on an equil ibrium system are changes in concentration of the reactants or products, changes in temperature, and changes in pressure or volume for gaseous equilibriaRead MoreEssay on Carbon Monoxide Poisoning1062 Words   |  5 Pagescalled hemoglobin. Each hemoglobin molecule can carry four oxygen molecules. Hemoglobin is the main transported of oxygen, carrying around 98% of the oxygen in the blood, with the remainder 2% carried in the dissolved state (Porth 2011). If all four subunits of a hemoglobin molecule are filled, it is said be to fully saturated. The ratio of the amount of oxygen molecules bound to hemoglobin to the oxygen carrying capacity of the hemoglobin is expressed as a percentage value. A hemoglobin moleculeRead MoreSickle Cell Anemia Essay593 Words   |  3 Pagesproduction of normal hemoglobin, which is an iron-containing protein in red blood cells that transports oxygen from the lungs to body tissues. The defective gene results in the production of abnormal hemoglobin known as hemoglobin S. If you have the disorder, you inherited one gene for hemoglobin S from each of your parents. The gene is recessive, so if you received a copy of the gene from just one parent, you are a carrier of the sickle cell gene. Under certain conditions, after hemoglobin S releases itsRead MoreThalassemia1449 Words   |  6 PagesBeta Thalassemia Beta thalassemia is an inherited blood disorder characterized by the abnormal production of a blood protein called hemoglobin. This condition is caused by a mutation within the gene that is responsible for the healthy production of hemoglobin. In healthy people, hemoglobin carries oxygen to tissues and cells throughout the body. Patients with beta thalassemia do not have adequate levels of oxygen within the blood, which can cause anemia. There are two main types of beta thalassemia
