  2. DNA nanotechnology - Wikipedia

    en.wikipedia.org/wiki/DNA_nanotechnology

    DNA nanotechnology, specifically, is an example of bottom-up molecular self-assembly, in which molecular components spontaneously organize into stable structures; the particular form of these structures is induced by the physical and chemical properties of the components selected by the designers. [19]

  3. Molecular models of DNA - Wikipedia

    en.wikipedia.org/wiki/Molecular_models_of_DNA

    Molecular models are useful in the design of structures for DNA nanotechnology. Here, individual DNA tiles (model at left) self-assemble into a highly ordered DNA 2D-nanogrid (AFM image at right). There are various uses of DNA molecular modeling in Genomics and Biotechnology research applications, from DNA repair to PCR and DNA nanostructures.

  4. Nucleic acid design - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_design

    Nucleic acid design is used in DNA nanotechnology to design strands which will self-assemble into a desired target structure. These include examples such as DNA machines, periodic two- and three-dimensional lattices, polyhedra, and DNA origami. [2]

  5. Molecular machine - Wikipedia

    en.wikipedia.org/wiki/Molecular_machine

    For example, they could be used to identify and destroy cancer cells. [ 83 ] [ 84 ] Molecular nanotechnology is a speculative subfield of nanotechnology regarding the possibility of engineering molecular assemblers , biological machines which could re-order matter at a molecular or atomic scale.

  6. DNA origami - Wikipedia

    en.wikipedia.org/wiki/DNA_origami

    The method of DNA origami was developed by Paul Rothemund at the California Institute of Technology. [6] In contrast to common top-down fabrication methods such as 3D printing or lithography which involve depositing or removing material through a tool, DNA Nanotechnology, as well as DNA Origami as a subset, is a bottom-up fabrication method.

  7. Nanopore sequencing - Wikipedia

    en.wikipedia.org/wiki/Nanopore_sequencing

    A natural MspA, while favorable for DNA sequencing because of shape and diameter, has a negative core that prohibited single stranded DNA(ssDNA) translocation. The natural nanopore was modified to improve translocation by replacing three negatively charged aspartic acids with neutral asparagines.

  8. Nucleic acid tertiary structure - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_tertiary...

    Three DNA conformations are believed to be found in nature, A-DNA, B-DNA, and Z-DNA. The "B" form described by James D. Watson and Francis Crick is believed to predominate in cells. [ 2 ] James D. Watson and Francis Crick described this structure as a double helix with a radius of 10 Å and pitch of 34 Å , making one complete turn about its ...

  9. DNA nanoball sequencing - Wikipedia

    en.wikipedia.org/wiki/DNA_nanoball_sequencing

    Workflow for DNA nanoball sequencing [1] DNA nanoball sequencing is a high throughput sequencing technology that is used to determine the entire genomic sequence of an organism. The method uses rolling circle replication to amplify small fragments of genomic DNA into DNA nanoballs. Fluorescent nucleotides bind to complementary nucleotides and ...
