تمثيل كيميائي: الفرق بين النسختين

This form of engineering is then contrasted with [[mechanosynthesis]], a hypothetical process where individual [[molecule]]s are mechanically manipulated to control reactions to human specification. Since [[photosynthesis]] and other natural processes create extremely complex molecules to the specifications contained in [[RNA]] and stored long-term in [[DNA]] form, advocates of [[molecular engineering]] claim that an artificial process can likewise exploit a chain of long-term storage, short-term storage, [[enzyme]]-like copying mechanisms similar to those in the [[Cell (biology)|cell]], and ultimately produce complex molecules which need not be [[protein]]s. For instance, [[sheet diamond]] or [[carbon nanotube]]s could be produced by a chain of non-biological reactions that have been designed using the basic model of biology.▼
