1 | The human genome includes five copies of the gene that produces beta-globin. | |
2 | Interference with the normal production of heme or globin leads to anemia. | |
3 | Antibody molecules (immunoglobulins) fall into several classes, each with its own functional characteristics. | |
4 | In the middle of these genes is a stretch of genetic code that clearly was once a sixth beta-globin gene. | |
5 | After phagocytosis and subsequent disruption of the cell membrane, Hgb is converted to heme and globin. |
