WebThe leading strand is synthesized continuously, while the lagging strand is synthesized in short fragments called Okazaki fragments, which are later joined by DNA ligase to form a continuous strand. 3. Transcription of the hemoglobin gene is initiated by the binding of RNA polymerase II to the TATA box located in the promoter region of the gene. WebErythropoiesis is the biological process that consumes the highest amount of body iron for heme synthesis. Heme synthesis in erythroid cells is finely coordinated with that of alpha (α) and beta (β)-globin, resulting in the production of hemoglobin, a tetramer of 2α- and 2β-globin chains, and heme as the prosthetic group.
