DNA research paves way for self-replicating materials

The possibility of engineering self-replicating nano-materials has emerged due to research into DNA (deoxyribonucleic acid), a self-replicating molecule whose 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. A recent study conducted by Junghoon Kim, Junwye Lee, Shogo Hamada, Satoshi Murata, and Sung Ha Park of Sungkyunkwan University and Tohoku University led to the design of a controllable self-replicating system that does not require proteins.
