This fact highlights a fundamental difference in granularity of vision between traditional synthetic chemistry and systems chemistry in a prebiotic context. Whilst yield, purity, and conversion

The interactions among individual components in CRNs can change over time and space [103][104][105][106][107], enabling regulatory functions to emerge that are dynamic and have limited predictability.
