It affects the functions of red blood cells of humans.
The correct statement is: It affects the functions of red blood cells of humans.
The statement that accurately describes sickle cell anemia is "It affects the functions of red blood cells of humans." Sickle cell anemia is a genetic blood disorder that affects the structure and function of red blood cells. It is caused by a mutation in the DNA, specifically in the gene that codes for hemoglobin, a protein responsible for carrying oxygen in red blood cells. This mutation leads to the production of abnormal hemoglobin, causing the red blood cells to become misshapen and fragile. As a result, the affected red blood cells have difficulty moving through blood vessels, leading to various complications and symptoms associated with sickle cell anemia.
