One of your patients, a six-year-old girl who suffers from Sickle cell anemia, an inherited blood disorder in which red blood cells are abnormally shaped and fragile, leading to a short supply of red blood cells.  These abnormal cells can also get stuck in small vessels, which prevent blood flow, leading to fatigue, pain, and other severe complications. Patients with sickle cell anemia produce defective beta-globin due to a point mutation that causes the change of a single amino acid residue. This is an example of what type of mutation? nonsense mutation   missense mutation   frameshift mutation   deletion mutation

Hematology

Hematology is the branch of biology. Hematology is the medical field that deals with the treatment of blood disorders and cancers, such as hemophilia, leukemia, lymphoma, and sickle-cell anemia. Hematologists and hematopathologists are medical professionals who specialize in illnesses of the blood and its components.
