Sickle cell anemia is a genetic disease that affects the shape and functionality of red blood cells. It is caused by a mutation in the DNA of the protein‚ hemoglobin‚ specifically in the beta chain. There are 531 base pairs in this DNA strand. Substitution or point mutation occurs‚ causing “GAG” to become “GTG”. This results in valine being created instead of glutamate. The mutation causes the hemoglobin to cling together in low oxygen levels and the red blood cell changes shape‚ preventing it from

Introduction There are many ways cells dispose of toxic molecules in order to maintain the necessary internal environmental conditions to survive. These toxic molecules are known as free radicals that contain an unpaired electron on the outer orbit (Proljsak et al.2013). Some examples of free radicals that can be found in the cell are superoxide (O2-)‚ hydrogen peroxide (H2O2) and even reactive metals like copper and iron. These free radicals are produced based on the environment the individuals
