Genes contain instructions for how our bodies grow and develop. They can be thought of as a kind of blueprint for the body, similar to the drawings used to build a building. Genes dictate in which order amino acids are produced, which in turn determines which proteins are produced. And, it is through regulating proteins that genes wield their crucial power over human biology. Proteins play an essential role in the functioning and development of the human body. If, however, there is something wrong on a genetic level, the right proteins, or the right quantities of a specific protein, may not be produced and lead to impaired functioning or disease.
