Many human diseases arise because of a "faulty" protein. Most of these diseases are genetic based. A typical example is sickle cell anemia, in which under certain conditions the mutation of a single amino acid in the hemoglobin molecule triggers a change of shape of the red blood cells.

Discuss one of such diseases affecting the health of human beings.

Hemophilia is one of the diseases that affect human beings' health as a result of mutations. 

Step-by-step explanation

Hemophilia results due to protein mutation or deficiency. During protein formation, changes that can occur in a codon can result in a faulty protein. In the process, the faulty protein will present as a missing protein in the body. In the case of hemophilia, individuals lack factor (VIII) or factor (IX). The lack of these proteins makes it difficult to perform blood clotting processes, and in the process, individuals present with blood clotting problems.  They bleed longer and can lose a lot of blood. The disease is often a genetic predisposition.
