The minimum length for this assignment is 1,200 words. Our understanding of genetic inheritance and the function of DNA in producing the characteristics of the individual have been developing for more than 150 years. Consider our current state of knowledge. Link genetic characteristics to DNA structure. 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? How does the significance of one class of proteins, the enzymes, relate to the importance of proper nutrition throughout life?
