Introduction. The Renaissance refers to the era in Europe from the 14th to the 16th century in which a new style in painting, sculpture and architecture developed after the Gothic.
Sickle cell disease is caused by a genetic abnormality in the gene for hemoglobin, which results in the production of sickle hemoglobin. When oxygen is released from sickle hemoglobin, it sticks together and forms long rods, which damage and change the shape of the red blood cell.eople who inherit only one sickle hemoglobin gene are carriers (sickle cell trait) and do not have anemia or painful sickle cell crises. They may, though, have a slightly higher incidence of certain conditions such as blood in the urine or urinary tract infections. About 2 million Americans have sickle cell trait.
A sickle cell is a malformed red blood cell. It is caused by a mutated gene inherited from one or both parents. If inherited from both parents the red cells are very malformed â¦ , causing sickle-cell anaemia. This is a serious illness, causing weakness and shortness of breath and often leading to an early death.n most gene therapy studies a 'normal' gene is inserted into the genome to replace an 'abnormal' disease-causing gene. A carrier molecule called a vector must b â¦ e used to deliver the therapeutic gene to the patient's target Cells.
