  2. 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.

  4. DNA - Wikipedia

    en.wikipedia.org/wiki/DNA

    DNA exists in many possible conformations that include A-DNA, B-DNA, and Z-DNA forms, although only B-DNA and Z-DNA have been directly observed in functional organisms. [14] The conformation that DNA adopts depends on the hydration level, DNA sequence, the amount and direction of supercoiling, chemical modifications of the bases, the type and ...

    "Children of color, families of color, have a smaller footprint in the DNA databases," Bischoff said. Bischoff said there is one tool that can be invaluable in helping identify these children.

  6. DNA synthesis - Wikipedia

    en.wikipedia.org/wiki/DNA_synthesis

    DNA replication also works by using a DNA template, the DNA double helix unwinds during replication, exposing unpaired bases for new nucleotides to hydrogen bond to. Gene synthesis, however, does not require a DNA template and genes are assembled de novo. DNA synthesis occurs in all eukaryotes and prokaryotes, as well as some viruses. The ...

  7. DNA sequencing - Wikipedia

    en.wikipedia.org/wiki/DNA_sequencing

    DNA sequencing methods currently under development include reading the sequence as a DNA strand transits through nanopores (a method that is now commercial but subsequent generations such as solid-state nanopores are still in development), [138] [139] and microscopy-based techniques, such as atomic force microscopy or transmission electron ...

  8. Nucleic acid - Wikipedia

    en.wikipedia.org/wiki/Nucleic_acid

    Deoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms. The chemical DNA was discovered in 1869, but its role in genetic inheritance was not demonstrated until 1943. The DNA segments that carry this genetic information are called genes.

  9. Recombinant DNA - Wikipedia

    en.wikipedia.org/wiki/Recombinant_DNA

    Recombinant DNA molecules are sometimes called chimeric DNA because they can be made of material from two different species like the mythical chimera. rDNA technology uses palindromic sequences and leads to the production of sticky and blunt ends. The DNA sequences used in the construction of recombinant DNA molecules can originate from any ...
