Transfer of Sequence Information and Replication of Diimine Duplexes
Journal of organic chemistry(2019)
摘要
The ability of the biopolymers RNA and DNA to store and transfer information is essential to life. Herein, we demonstrate template-directed replication in a set of dimer duplexes that use reversible covalent bonds to form base-pairing interactions. Binary sequence information was encoded as a sequence of aniline and benzaldehyde subunits linked together by a diethynyl benzene backbone. These dimers formed sequence-specific, imine-linked duplexes, which could be separated and used as templates for the synthesis of daughter duplexes with identical sequences.
