III. Open-end questions
1. The human genome contains approximately 20,000 protein-coding genes, yet human cells are capable of synthesizing well over 100,000 distinct functional polypeptides.

b) Contrast the evolutionary and systemic consequences of a point mutation occurring within an exon (protein-coding sequence) versus a mutation occurring within an upstream regulatory sequence (such as an enhancer). Focus your discussion on the concept of Pleiotropy and organismal viability. (5 points)
