What is synthetic biology?

1. Synthetic Biology aims to harness the emergent properties of the central dogma for biotechnological and human use.This description of the field is comprehensive.Synthetic biology research is at the the forefront of engineering the three tiers of biological systems.Contributions from system biology have broadened our ability to understand and engineer biological networks.
2. This system has 3 tiers ,specifically:(1)The central dogma process units (transcription and translation) and associated streams(DNA,RNA and protein),(2)the intrinsic regulatory mechanisms in the cells, and (3) the extrinsic physical and chemical environment of the cells.Synthetic biology is developing tools to modify and control each unit and stream in this process.
