Sample Question
A 44-year old woman presents to her physician with loss of appetite, fatigue, muscle weakness and depression. Initial blood analysis shows she has anemia. A bone marrow aspirate confirmed the suspicion that she has a megaloblastic anemia. Serum folic acid level was 2.9 ng/m1 (normal= 6-15), Her serum B12 level was 153 pg/ml (normal=150-75C). The patient's megaloblastic anemia is most likely caused by

A decreased synthesis of rnethionine

A decreased conversion of dUMP to dTMP

A decrease in the synthesis of oxaloacetate

A decrease in the leves of succinyl CoA.

A decreased synthesis of dUMP.
