2. (Short Answer)
Describe Sickle Cell Anemia
ANSWER.
People Who Inherit A Mutant Copy Of The Β-Globulin Protein From Both Parents Have
Sickle-Cell Anemia. The Mutant Β-Globulin Causes The Hemoglobin Within Red Blood
Cells To Distort When The Oxygen In The Blood Is Low, And In Fact, Deforms The Cell
Shape So Much That The Distorted Cells Break Very Easily. In Turn, The Loss Of The
Broken Cells Lowers The Total Number Of Red Blood Cells, Resulting In Anemia
In Addition, The Odd Shape Of The Red Blood Cells Actually Causes Blockages In
Small Blood Vessels, Which Causes Pain And Damage To The Brain, Heart, Muscles,
And Kidneys. The Condition Is Especially Exacerbated Under Atmospheric Conditions
Where Oxygen Is Lower, So People With Sickle-Cell Anemia Can Become Extremely
Sick At High Altitudes.
