Texas A&M, BIOL 112
Excerpt: ... Write the equation for calculating allele frequencies. Be able to solve a problem. When we tasted PTC paper in class (see page 5), the percentage of those who are tasters are represented by the equation p2+2pq, why? Why are nontasters represented by q 2? The percentages of tasters are rep by p2+2pq, because ppl who can taste have a dominant allele and the nontasters are rep by q2 because the homozygous recessive gene cannot taste PTC. p+q=1 Make sure that you understand the experiment where we ran the gels. (electrophoresis) What did the bands represent? Why were we looking at those bands? What does this experiment have to do with malaria and sickle cell anemia ? The gel electrophoresis was when we looked at 3 different samples of blood from South Africa, Sudan, and Dem Rep of the Congo. We were looking at those bands to determine which country needed the most malaria control funds. The bands in the gel rep the different allele types. We were looking at the bands to determine which country had the most ...

Excerpt: ... ld flat or coordinated by four nitrogen ligands that form to make a ring shape. In deoxyhemoglobin the nitrogen binds to the iron from an amino acid (part of helix, part of globin). The front of the iron is not bound to anything and contracts outward because it isnt bound to anything on its backside to equal the force of the nitrogens pull. When deoxyhemoglobin binds to oxygen it becomes oxyhemoglobin. In the oxyhemoglobin structure, the oxygen has bound to the non-bound section of the iron and balanced out the bond. The helix then moves, interaction change between hemes and chemistry and geometry changes and makes the next alpha or beta globin more likely to bind to the oxygen tighter. Figure 2: The molecule shown is a model of human deoxyhemoglobin S, or the mutant form of hemoglobin that defines sickle cell anemia . It was created in RasMol version 2.6 by Roger Sayle. The 3D coordinates were determined by x-ray diffraction by D.J. Harrington, K. Adachi, and W.E. Royer Jr: The high resolution cr ...

Sicke Cell Abstract
Villanova, BIO 2105
Excerpt: ... Beta Hemoglobin and Sickle Cell Anemia The episodes of pain resulting from Sickle Cell Anemia can range from mild to severe symptoms. Common symptoms are hand-foot syndrome, fatigue, paleness, shortness of breath, pain in any body organ or joint, eye problems, and yellowing of skin and eyes. The gene that encodes beta hemoglobin is found in the human genome and located on chromosome 11. This gene has 3 exons and 2 introns and is 1606 base pairs long. The coding of valine instead of glutamine in position 6 of the Hb beta chain results from the mutation of substituting thymine for adenine in the sixth codon of the beta chain. Hemoglobin (Hb) S usually carries oxygen, but begins to form semisolid aggregates when oxygen is unloaded to the tissues. The hemoglobin S aggregates distort the red blood cells and cause them to lose elasticity. At first, hemoglobin S retains its ability to return to its soluble form, and the red cells can regain their elasticity upon reoxygenation. The resulting hemoglobin has the physic ...
