Sickle cell anemia causes an oxygen deficiency in different parts of the body, which can be dangerous. For instance, if developing cells do not receive enough oxygen, their growth can be stunted. Often, a person with sickle cell anemia will have a low amount of red blood cells because sickle cells are abnormally frail, which can cause anemia. The abdominal and chest pain experienced by someone with sickle cell anemia is caused by arteries that have become obstructed by a buildup of sickle cells. If sickle cells cause spleen damage, the body may become more prone to infection. Sickle cell anemia can also damage blood vessels in the eyes, decreasing vision.
It is a type of disorder which occurs inside the red blood cells or RBC's of the blood medium. And is mainly caused by the deficiency in the oxygen molecules inside the blood medium leading the nerves and the cells to have lack of oxygen.
As, the target cells become more sickle in shape and they are unable to carry on the transportation of the oxygen,O₂ molecules through the given path way or arteries inside the circulatory system present in the body.
<u>Target Cells in the Body and Cause:</u>
It is mainly caused by the deficiency in the level of oxygen,O₂ molecules inside the blood medium, as its not because of the lack of oxygen present in the air but due to receiving an abnormal gene by the person leads to abnormality in the structure or shape of the hemoglobin over all. Making the RBC's unable to carry enough oxygen to all the cells.
<u>Diseases or disorders caused by the sickle anemia:</u>
Due, to lack of oxygen in the blood medium causes the cells to die and remain under nourished.
Damage to the nerves and the arteries is caused leading to some of the heart diseases and the liver disorders.
Some body parts may stop working due to less supply of oxygen to them.
Most of the patient's body become pale and less developed both physically and mentally.
A
person does have basic human rights and one is the freedom of expression. Though
this is the case, we should understand that our right to freely express
ourselves (from political to religious views), it does not necessarily give us
the right to impede another person’s. A play with words can easily hurt or even
harass other people, and in return may be a form of human right violation.
This problem is talking about the lac operon and the gene expression of lac operon. If the gene is turned off, then transcription, the generation of mRNA won't occur.
