Based on your understanding of genetic code,explain the formation of any abnormal hemoglobin molecule?

A 30 - year - old woman was undergoing therapy for b-thalassemia,a recessive trait caused by absence of or reduced synthesis ofthe hemoglobin b chain, a subunit of the oxygen-carrying moleculein red blood cells. In this condition, red blood cells are rapidlydestroyed, freeing a large amount of iron, which is deposited in tissuesand organs. The blood transfusions the patient had received every twoor three weeks since the age of 7 to stave off anemia were furtheraggravating iron buildup. Her major organs were showing damage, andshe was in danger of death from cardiac disease. Her physician suggestedthat she consider undergoing a hematopoietic (bone marrow)stem cell transplant (HSCT). Since these stem cells give rise to redblood cells, such a transplant could potentially restore her health. Whilethis might seem like an easy decision, it is not. Advanced cases havea high risk (almost 30 percent) for transplantation-related death. At thispoint, the woman is faced with a difficult and…

How can a single nucleotide insertion in the beta globin gene generate a phenotypic change in the ability of the red blood cell to transport oxygen?

Determine which statements could be used as evidence to support the argument that "DNA influences the proteins that are made" and which statements are just facts. [Select all that apply.] The HBB gene that makes beta-globin has several abnormal alleles, including HbS, HbC, and HbE. Sickle cell disease has been successfully treated using bone marrow transplantation in children and adults. The symptoms of sickle cell anemia may not appear in individuals who only carry one HbS allele, but are always apparent when both alleles are HbS. If oxygen is removed from red blood cells made by two HbS alleles, the cell will form a sickle shape.

In Sickle Cell Anemia, the production of both of the A and S beta-globin peptides in carriers suggests that the Hb beta^A and the Hb beta ^S genes^1 dominance relation is… A) Hb beta A is dominant B) Hb beta S is dominant C) Hb beta A and Hb beta S are codominant D) Hb beta A and Hb beta S are incompletely dominant

Consider two different genes that are highly expressed in the tissue of your spleen (but not expressed in any other tissue in your body). Which of the following describes something that these two different genes have in common? A) Both of these genes must have the same set of control element sequences associated with them. B) Both of these genes must be present in spleen cells, but absent from the cells in the rest of your body. C) Both of these genes must be located on the same chromosome. D) Both of these genes must be the same length. .
