Which is the last stage with a nucleolus in erythropoiesis?

Nucleolus presence signals active ribosome production needed for rapid protein synthesis during early red cell development. As erythropoiesis progresses, the nucleus condenses and the nucleolus disappears, reflecting a shift away from intense RNA synthesis toward maturation and enucleation. Among the stages listed, prorubricyte is the last one where a nucleolus can still be seen; beyond this point, the nucleolus is lost as the cell becomes more mature (rubricyte and later stages) and ultimately enucleates to form a reticulocyte.
