The synthesized double-helical monometallofoldamers exhibiting controllable chirality switching can lead to the development of novel artificial supramolecular systems for molecular information ...

That realization was a breakthrough. It instantly suggested how hereditary information is stored and how cells duplicate their DNA when they divide. The duplication begins with the two strands of DNA ...
