Abstract
In this chapter, we have seen that a cell is a highly organized system. This organized character begins at the bottom of the scale, where proteins, DNA, and other molecules associate to form supramolecular assemblies. At a higher level, the genome is a far more intricately organized system. However, notwithstanding its intricacies, the genome is an immaculately functioning system. Importantly, we have seen that such organizations give rise to emergent properties not found in their constituting parts. Thus the emphasis on studying biology using chemical tools and concepts must focus on the integrative character of the biological systems.
