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.
2. Digestion of DNA with a restriction endonuclease. Extracted DNA is treated with a restriction endonuclease, which is an enzyme that will cut double stranded DNA whenever a specific DNA sequence occurs. The enzyme most commonly used for forensic DNA analysis is HaeIII, which cuts DNA at the sequence 5'-GGCC-3'.maller DNA fragments move more rapidly through the pores of the gel matrix than larger DNA fragments. The result is a continuous separation of the DNA fragments according to size, with the smallest DNA fragments moving the greatest distance away from the origin.
