. Mutations in an autosomal gene in humans cause aform of hemophilia called von Willebrand disease(vWD). This gene specifies a blood plasma proteincleverly called von Willebrand factor (vWF). vWFstabilizes factor VIII, a blood plasma protein specified by the wild-type hemophilia A gene. Factor VIIIis needed to form blood clots. Thus, factor VIII is rapidly destroyed in the absence of vWF.Which of the following might successfully be employed in the treatment of bleeding episodes in hemophiliac patients? Would the treatments workimmediately or only after some delay needed forprotein synthesis? Would the treatments have only ashort-term or a prolonged effect? Assume that allmutations are null (that is, the mutations result in thecomplete absence of the protein encoded by the gene)and that the plasma is cell-free.a. transfusion of plasma from normal blood into avWD patientb. transfusion of plasma from a vWD patient into adifferent vWD patientc. transfusion of plasma from a hemophilia A…

Mouse models for human genetic diseases are potentially powerful tools to help geneticists understand thecause of the aberrant phenotypes and develop newtherapeutic measures. However, such mice are not always as useful to investigators as it might seem at firstglance. Suppose that you have a mouse knockoutmodel for a human disease caused by homozygosityfor a null allele of a gene. Discuss how the followingsituations might complicate investigations of the human disease based on this mouse model.a. Mice have a shorter life span than humans.b. Mice homozygous for certain knockout mutationsdie in utero.c. Mouse genomes may have additional copies of thegene whose mutation causes the disease in humans.

Which type of mutation stops the translation of an mRNA molecule? 2. Sickle Cell Anemia Sickle cell anemia is the result of a type of mutation in the gene that codes for part of the hemoglobin molecule Hemoglobin carries oxygen in your red bloods cells. The mutation causes these red blood cells to become stife sickle-shaped when they release their oxygen.
