Question

Sickle-cell anemia is a genetic disease that causes red blood cells to have an odd shape. The odd shape prevents the blood cells from carrying as much oxygen as they should. What is the most likely cause for this disease?

Answer 1

"Normal red blood cells are rounded and disk-shaped. In sickle cell anemia, some red blood cells become deformed, so they look like sickles used to cut wheat. These unusually shaped cells give the disease its name. Sickle cell anemia is one of a group of disorders known as sickle cell disease."
