Rating Newest Oldest. Best Answer: DNA fingerprinting is a laboratory procedure that requires six steps: 1: Isolation of DNA. DNA must be recovered from the cells or tissues of the body. Only a small amount of tissue-like blood, hair, or skin-is needed.For example, the amount of DNA found at the root of one hair is usually sufficient. 2: Cutting, sizing, and sorting. Special enzymes called restriction enzymes are used to cut the DNA at specific places.he distribution of DNA pieces is transferred to a nylon sheet by placing the sheet on the gel and soaking them overnight. 4-5: Probing. Adding radioactive or colored probes to the nylon sheet produces a pattern called the DNA fingerprint.
