Synthetic biologiy sits at t intersection of dicular biology, incorporation, computer sciency, and chemistry. Unlike traditional genetic equidering, which typically makes small, target changes to existing organisms, synthetic biology aims to construct entirely new biological parts, devices, and systems - or to reprogram existing organisms in principled, preventable ways.
