Consider our current state of knowledge.
Link genetic characteristics to DNA structure.
Describe the steps in the process of protein synthesis.
Explain how DNA through the process of protein synthesis is responsible for the ultimate expression of the characteristics in the organism.
Describe how interference in protein synthesis can result in disruption of cellular and bodily processes?

One important class of proteins are enzymes, which control countless processes within our bodies. Considering that the building blocks of proteins are amino acids, explain how poor nutrition can disrupt many important functions in our bodies.
