Solution
The correct option is A Sickle cell anaemia An example of the disease of molecular mutations is sickle cell anemia. Sickle cell anemia is caused by a mutation in the hemoglobin-Beta gene found on chromosome 11. It is an autosomal recessive disorder. Normally, our red blood cells are flexible and round, moving easily through your blood vessels. In sickle cell anemia, the red blood cells become rigid and sticky and are shaped like sickles or crescent moons. These irregularly shaped cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body.
