D)Iron and liver disease

Question

Quizplus · Accepted Answer

Megaloblastic anemia is most often caused by deficiencies of vitamin B₁₂ and folate. These two components are essential for the synthesis of DNA, which is necessary for the production of red blood cells. Deficiencies in either of these components can result in megaloblastic anemia, which is characterized by abnormally large and immature red blood cells. Iron deficiency anemia and liver disease can also cause anemia, but they are not typically associated with megaloblastic anemia. Iron is essential for the production of hemoglobin, but it is not directly involved in DNA synthesis. Transferrin is a protein that binds to and transports iron in the blood, but a deficiency of transferrin alone would not cause anemia. Ferritin is a protein that stores iron in the body, but a deficiency of ferritin alone would not cause anemia.
