Part 2/8:
At its core, the PCR process allows scientists to amplify a singular molecule to a measurable size. This powerful technique implies that almost any molecule present in a biological sample can be detected, leading to the paradox of discovering what is often present in minuscule quantities. This ability prompts existential reflections, akin to Buddhist philosophy, suggesting that while we can amplify and measure such small amounts, it may not hold significant meaning regarding health outcomes.
