Is it possible to engineer self-replicating nanomaterials? It could be if we borrow nature's building blocks. DNA is a self-replicating molecule where its component parts, nucleotides, have specific chemical interactions that allow for the design of self-assembled structures. In biological systems, DNA replicates with the aid of proteins.
