DNA extraction is the process of isolating DNA from the cells of an organism isolated from a sample, typically a biological sample such as blood, saliva, or tissue. It involves breaking open the cells, removing proteins and other contaminants, and purifying the DNA so that it is free of other cellular components.

In 1970 Hamilton Smith's lab discovered restriction enzymes that allowed DNA to be cut at specific places, enabling scientists to isolate genes from an organism's genome. [35] DNA ligases that join broken DNA together had been discovered earlier in 1967, [ 36 ] and by combining the two technologies, it was possible to "cut and paste" DNA ...
Rapid DNA is a "swab in-profile out" technology that completely automates the entire DNA extraction, amplification, and analysis process. Rapid DNA instruments are able to go from a swab to a DNA profile in as little as 90 minutes and eliminates the need for trained scientists to perform the process.
Plasmid miniprep. 0.8% agarose gel ethidium bromide-stained.. A plasmid preparation is a method of DNA extraction and purification for plasmid DNA.It is an important step in many molecular biology experiments and is essential for the successful use of plasmids in research and biotechnology.
Electroelution is a method used to extract a nucleic acid or a protein sample from an electrophoresis gel by applying a negative current in the plane of the smallest dimension of the gel, drawing the macromolecule to the surface for extraction and subsequent analysis. [2]

In DNA extraction, after separating DNA from other cell constituents in water, DNA is precipitated out of solution by neutralizing it with positively charged ions. The addition of ethanol to the solution is necessary to reduce the polarity of the solvent and allow the positively charged ions to interact with the negatively charged phosphate ...
