# Recombinant DNA **Domain:** Molecular Biology / Genetic Engineering **Doc Type:** Canonical Technology Node **Maturity:** Foundational ## Definition **Recombinant DNA** technology joins DNA from different sources and introduces constructed molecules into a host where they can be replicated or expressed. ## Evolutionary Nexus Paul Berg's early recombinant molecules and the Cohen–Boyer cloning system changed biological inheritance from an observed process into a directly engineered substrate. [[articles/The Evolutionary Roots of Silicon Valley|The Evolutionary Roots of Silicon Valley]] places this work beside computing because both fields were learning to manipulate encoded generative systems. ## Continuity Context DNA can remain functional after transfer across organisms, demonstrating substrate portability of a biological instruction sequence. The receiving cell still supplies transcription, translation, metabolism and regulation. Portability therefore proves dependence on an interpreter, not independence from substrate. ## Governance Context Recombinant DNA also produced the Asilomar precedent: capability created a duty to define containment and prohibited experiments before consequences were fully known. ## Sources / Provenance - Nobel Prize, Paul Berg facts: https://www.nobelprize.org/prizes/chemistry/1980/berg/facts/ - Stanford Cohen laboratory: https://med.stanford.edu/sncohenlab/stan-cohen.html ## See Also [[wiki/Asilomar Conference|Asilomar Conference]], [[wiki/Biological Bootloader|Biological Bootloader]], [[wiki/Receiving Substrate|Receiving Substrate]], [[wiki/Genentech|Genentech]]
