Self-replication
What is it? Self-replication is a means by which an individual can duplicate itself. Such molecular photocopying occurs when a reaction product directs its own formation from component parts. This has been hypothesized to be a route by which primitive life may have sustained itself. How does it work? It involves product-directed assembly of components to form a new product. The simplest self-re...
متن کاملSelf-Replication and Self-Assembly for Manufacturing
It has been argued that a central objective of nanotechnology is to make products inexpensively, and that self-replication is an effective approach to very low-cost manufacturing. The research presented here is intended to be a step towards this vision. We describe a computational simulation of nanoscale machines floating in a virtual liquid. The machines can bond together to form strands (chai...
متن کاملStatistical physics of self-replication.
Self-replication is a capacity common to every species of living thing, and simple physical intuition dictates that such a process must invariably be fueled by the production of entropy. Here, we undertake to make this intuition rigorous and quantitative by deriving a lower bound for the amount of heat that is produced during a process of self-replication in a system coupled to a thermal bath. ...
متن کاملDoes self-replication imply evolvability?
The most prominent property of life on Earth is its ability to evolve. It is often taken for granted that self-replication– the characteristic that makes life possible–implies evolvability, but many examples such as the lack of evolvability in computer viruses seem to challenge this view. Is evolvability itself a property that needs to evolve, or is it automatically present within any chemistry...
متن کاملSelf-replication in colloids with asymmetric interactions.
Self-replication is a ubiquitous process in organisms. Understanding the key ingredients of self-replication is critical for developing self-sustaining systems in the laboratory. Moreover, finding the optimal conditions to generate accurate replicas and adequate output can accelerate industrial processes enormously. Here, we propose a scheme for self-replication where asymmetric interactions in...
