What are the 4 steps used to extract DNA?
This is an ambiguous question: are we talking about obtaining DNA samples from the person, are we talking about obtaining DNA from the specimen? Obtaining DNA from a person is as simple as swabbing the person's buccal mucosa, which is inside a person's cheek. Obtaining DNA from a specimen is a process by which DNA is extracted by using chemicals that emulsify the cells to extract the DNA, then centrifuging the mixture to extract it. The DNA is then pipetted into a radioactive gel that identifies each strand's DNA structure. The preparation is then x-rayed to reveal the unique DNA structure.
