48. Sickle cell anemia (SCA) is an inherited blood disorder resulting from abnormally shaped hemoglobin in red blood cells. Affected individuals often experience anemia and pain caused by blocked blood vessels. SCA is caused by a point mutation in the amino acid chain that results from glutamic acid being replaced by valine. What type of mutation causes sickle cell anemia? Select one: a. frameshift mutation b. substitution c. silent mutation d. deletion

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.
