    Sickle-cell anemia is a disease caused due to the abnormality in

    A)  white blood cells

    B)       red blood cells

    C)       thrombocytes

    D)       blood plasma composition

    Correct Answer: B

    Solution :

    Sickle cell anemia is an inherited blood disorder that causes chronic anemia, periodic episodes of pain, and other complications. In sickle cell anemia, the red blood cells become rigid and shaped like crescents, or sickles, rather than being flexible and round. This change in shape prevents red blood cells from getting into small blood vessels. As a result, the tissues do not get enough oxygen. Lack of oxygen can cause pain and damage in the arms, legs, and organs (e.g., spleen, kidney, brain).
