Simply put, DNA Extraction is the removal of deoxyribonucleic acid (DNA) from the cells or viruses in which it normally resides. DNA is the precipitated by mixing with cold ethanol or isopropanol and then centrifuging. 2  The DNA is insoluble in the alcohol and will come out of solution, and the alcohol serves as a wash to remove the salt previously added.
What is DNA sequencing? Sequencing DNA means determining the order of the four chemical building blocks - called bases - that make up the DNA molecule. The sequence tells scientists the kind of genetic information that is carried in a particular DNA segment. For example, scientists can use sequence information to determine which stretches of DNA contain genes and which stretches carry regulatory instructions, turning genes on or off. In addition, and importantly, sequence data can highlight changes in a gene that may cause disease.
