Journal Article
Chemical copying of connectivity
2002
Overview
Three-dimensional DNA nanoscaffolds such as supramolecular tetrahedra can self-assemble from tris-oligonucleotidyls — synthetic three-armed building blocks in which three identical or non-identical short DNA sequences are connected by a tris-linking backbone

. Here we show that the connectivity information contained in these building blocks can be copied by using template-directed tris-linking. This finding is a crucial step towards the replication of nanoarchitectures that are based on tris-oligonucleotidyls and to the realization of artificially self-replicating systems on a nanometre scale.
