Web16 apr. 2024 · Megaloblastic anemia: impairments in DNA synthesis (e.g. folate, B12 deficiency, orotic aciduria) result in abnormal development of the nucleated erythroblasts (RBC precursors) in the marrow. These precursor cells cant make DNA properly, so their division is delayed while cytoplasmic protein synthesis continues unhindered (“nuclear ... WebA characteristic feature of cobalamin de ciency is nuclear-cytoplasm asynchrony in erythroid maturation, whereby maturation of the nucleus is delayed relative to that of the cytoplasm because cobalamin is essential for DNA synthesis 4, 5. Cobalamin de ciency is very rare in childhood, and is seen mainly in children
