  2. DNA nanotechnology - Wikipedia

    en.wikipedia.org/wiki/DNA_nanotechnology

    Structural DNA nanotechnology, sometimes abbreviated as SDN, focuses on synthesizing and characterizing nucleic acid complexes and materials where the assembly has a static, equilibrium endpoint. The nucleic acid double helix has a robust, defined three-dimensional geometry that makes it possible to simulate, [ 26 ] predict and design the ...

  3. Spherical nucleic acid - Wikipedia

    en.wikipedia.org/wiki/Spherical_nucleic_acid

    Due to their structure and function, SNAs occupy a materials space distinct from DNA nanotechnology and DNA origami, [20] [21] (although both are important to the field of nucleic acid–guided programmable materials. [22] With DNA origami, such structures are synthesized via DNA hybridization events.

  4. Nucleic acid design - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_design

    Nucleic acid design is central to the fields of DNA nanotechnology and DNA computing. [2] It is necessary because there are many possible sequences of nucleic acid strands that will fold into a given secondary structure, but many of these sequences will have undesired additional interactions which must be avoided.

  5. Nucleic acid secondary structure - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_secondary...

    The stem-loop structure (also often referred to as an "hairpin"), in which a base-paired helix ends in a short unpaired loop, is extremely common and is a building block for larger structural motifs such as cloverleaf structures, which are four-helix junctions such as those found in transfer RNA. Internal loops (a short series of unpaired bases ...

  6. Nucleic acid quaternary structure - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_quaternary...

    The term has also been used to describe the hierarchical assembly of artificial nucleic acid building blocks used in DNA nanotechnology. [3] The quaternary structure of DNA refers to the formation of chromatin. Because the human genome is so large, DNA must be condensed into chromatin, which consists of repeating units known as nucleosomes.

  7. Nucleic acid structure - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_structure

    DNA structure and bases A-B-Z-DNA Side View. Tertiary structure refers to the locations of the atoms in three-dimensional space, taking into consideration geometrical and steric constraints. It is a higher order than the secondary structure, in which large-scale folding in a linear polymer occurs and the entire chain is folded into a specific 3 ...

  8. Molecular models of DNA - Wikipedia

    en.wikipedia.org/wiki/Molecular_models_of_DNA

    The chemical structure of DNA is insufficient to understand the complexity of the 3D structures of DNA. In contrast, animated molecular models allow one to visually explore the three-dimensional (3D) structure of DNA. The DNA model shown (far right) is a space-filling, or CPK, model of the DNA double helix. Animated molecular models, such as ...

  9. Nanostructure - Wikipedia

    en.wikipedia.org/wiki/Nanostructure

    A nanostructure is a structure of intermediate size between microscopic and molecular structures. Nanostructural detail is microstructure at nanoscale. In describing nanostructures, it is necessary to differentiate between the number of dimensions in the volume of an object which are on the nanoscale.
