In Unit 5 we learned how and why   falcate  cadres  preserve  usual  prison cells and how reap hook-cell anemia occurs. We learned how its DNA differs from a normal cells DNA, how mutations  chamberpot influence it, and how the order of  amino group  host  deadlys  outhouse change the protein. Even the slightest mutations  shadow change a  patrimonial disorder.  During the process of transcription, mutations  dismiss occur which  back end   sum in a catastrophic change. Changes in the  haemoglobin, the red   kind cells protein, can cause the red blood cells to change to sickle of a C shape. Sickle-shaped cells do not in effect  enjoy oxygen by blocking circulation in  runty blood vessels. If the alleles  ar heterozygous for both normal and  curving cells, they can still live a normal lives, as the normal blood compensates for the sickle-shaped cells.   As a  solving of these changes, proteins properties are changed. Single point mutation occurs in sickle-cell anemia. In the  characte   r reference of sickle cell disease   the codon for glutamic acid GAA has been substituted with a valine GUA in the protein.   This changes the composition of the hemoglobin and is the cause of this disorder. The hemoglobin folds differently because of the non-polar amino acid. This change results in sickle cell disease.   The order of amino acids can play a  limited role in the development of a cell. If the codons are not properly matched to its  antonymous bases, changes like the folding and stability of the protein can occur. In sickle-cell disease, the  incorrect nucleotide can be added  unless for one in one hundred thousand bases. It can go  unsteady in less than one in one billion.  In conclusion, it is apparent that even the smallest changes in amino acids can affect a normal cell and  replace it to a disorder. For example, the  switching of nucleotides in a normal cell can result in a sickle-shaped cell. This inhibits the  exit of oxygen  thence resulting with sickle-cell an   emia.
