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.

DNA purification is a powerful tool used in life sciences and biotech labs to extract pure DNA for high-throughput workflows. Any impurities or contaminants in the DNA can affect the downstream applications and determine the result of your research. Today, a range of techniques are available to clean DNA, which include organic extraction

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7122149/
McCormick et al. introduced a new DNA extraction method involving solid-phase extraction in 1989 . They used an insoluble siliceous core particle rather than liquid phenol. The function of this siliceous core particle is similar to that of phenol, but it has a few advantages in that it is safer, and cross-contamination can be reduced.

The extraction of DNA from a cell is often a first step for scientists who need to obtain and study a gene. The total cell DNA is used as a pattern to make copies (called clones) of a particular gene. These copies can then be separated away from the total cell DNA, and used to study the function of that individual gene.

Isolating, Cloning, and Sequencing DNA. Until the early 1970s DNA was the most difficult cellular molecule for the biochemist to analyze. Enormously long and chemically monotonous, the string of nucleotides that forms the genetic material of an organism could be examined only indirectly, by protein or RNA sequencing or by genetic analysis.
