  • This study introduces RNA origami nanotubes as self-assembling cytoskeleton mimics for synthetic cells. Expressed in vesicles from DNA templates, these RNA structures reach micrometre lengths, deform membranes and exhibit different phenotypes.

  • An autonomous DNA-origami nanomachine powered by the chemical energy of DNA-templated RNA-transcription-consuming nucleoside triphosphates as fuel performs rhythmic pulsations is demonstrated. In combination with a passive follower, the nanomachine acts as a mechanical driver with molecular precision.

  • A six-helix bundle DNA structure called meta-DNA has now been assembled and shown to possess some structural properties similar to those of single-stranded DNA. Two meta-DNAs containing complementary ‘meta-base pairs’ are shown to form double helices. Meta-DNA building blocks are also used to construct a series of DNA architectures and to perform a hierarchical strand-displacement reaction.
