People with two copies of the sickle cell gene have the disease. People who carry only one copy of the sickle cell gene do not have the disease, but may pass the gene on to their children. Abnormal hemoglobin, called hemoglobin S, causes sickle cell disease (SCD). The problem in hemoglobin S is caused by a small defect in the gene that directs the production of the beta globin part of hemoglobin. This small defect in the beta globin gene causes a problem in the beta globin part of hemoglobin, changing the way that hemoglobin works.

The question shows the results of a gel
electrophoresis, which shows DNA fragments of the victim and two suspects,
suspect 1 and suspect 2. A comparison of the five DNA fragments of the victim,
A to E, reveals that the victim and suspect 1 both have the DNA fragment b.
A
visual comparison of the gel electrophoresis results should reveal that Suspect
1 has a DNA fragment that matches victim DNA fragment B.<span>The visuals can be seen in the attachment.</span>
