  2. DNA origami - Wikipedia

    en.wikipedia.org/wiki/DNA_origami

    DNA origami object from viral DNA visualized by electron tomography. [1] The map is at the top and atomic model of the DNA colored below. (Deposited in EMDB EMD-2210) . DNA origami is the nanoscale folding of DNA to create arbitrary two- and three-dimensional shapes at the nanoscale.

  3. Molecular model - Wikipedia

    en.wikipedia.org/wiki/Molecular_model

    Molecular models may be created for several reasons – as pedagogic tools for students or those unfamiliar with atomistic structures; as objects to generate or test theories (e.g., the structure of DNA); as analogue computers (e.g., for measuring distances and angles in flexible systems); or as aesthetically pleasing objects on the boundary of ...

  4. Molecular models of DNA - Wikipedia

    en.wikipedia.org/wiki/Molecular_models_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 the wire, or skeletal, type shown at the top of this article, allow one to visually explore the three-dimensional (3D) structure of DNA. Another type of DNA model is the space-filling, or CPK, model.

  5. Oligonucleotide synthesis - Wikipedia

    en.wikipedia.org/wiki/Oligonucleotide_synthesis

    Oligonucleotide synthesis is the chemical synthesis of relatively short fragments of nucleic acids with defined chemical structure ().The technique is extremely useful in current laboratory practice because it provides a rapid and inexpensive access to custom-made oligonucleotides of the desired sequence.

  6. Rule-based modeling - Wikipedia

    en.wikipedia.org/wiki/Rule-based_modeling

    Rule-based modeling is a modeling approach that uses a set of rules that indirectly specifies a mathematical model. The rule-set can either be translated into a model such as Markov chains or differential equations, or be treated using tools that directly work on the rule-set in place of a translated model, as the latter is typically much bigger.

  7. Nucleic acid design - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid_design

    A geometrical model of a DNA tetrahedron described in Goodman, 2005. [10] Models of this type are useful for ensuring that tertiary structure constraints do not cause excessive strain to the molecule. Geometrical models of nucleic acids are used to predict tertiary structure. This is important because designed nucleic acid complexes usually ...

  8. Daisy chaining DNA - Wikipedia

    en.wikipedia.org/wiki/Daisy_chaining_DNA

    An example is a three element daisy chain; element C would be used to activate element B, element B would be used to activate element A. Element C would be the original guide molecule put into the DNA sequence by using molecular scissors with the molecule attached. These scissors cut the DNA sequence and inputs the new guide molecule.

  9. Scaffolding (bioinformatics) - Wikipedia

    en.wikipedia.org/wiki/Scaffolding_(bioinformatics)

    Optical mapping is the process of immobilizing the DNA on a slide and digesting it with restriction enzymes. The fragment ends are then fluorescently tagged and stitched back together. For the last two decades, optical mapping has been prohibitively expensive, but recent advances in technology have reduced cost significantly.
