If they are partial prints. If the prints belong to someone that has already been excluded, i.e., investigators or persons who are innocent.

The use of RFLPs in generic fingerprinting is based on the ability of restriction enzymes to dissect DNA into small fragments. There are many kinds of restriction enzymes made to cut various DNA sequences.

Gel electrophoresis separates DNA fragment on the basis of their size. In DNA fingerprinting or DNA typing given sample is cut up with restriction enzymes and run through electrophoresis and results are analyzed to check for DNA polymorphism between the given sample and a sample form suspect. In nutshell gel electrophoresis is boon for the people in forensics.
Genetic fingerprinting can match a hair to an individual person. It's now a common method of crime detection, if the root of the hair is with the hair. DNA can be extracted from the root.

DNA Fingerprinting
DNA fingerprinting offers a technique to single out an individual with a 100% success rate. A persons DNA fingerprint is unique and this quality becomes very useful in forensic applications. Therefore, there is much interest in DNA fingerprinting. In research however, fingerprinting is used to differentiate between different strains of a certain species of bacteria for epidemiological studies
DNA fingerprinting
The sequence of DNA that is repeated varies significantly from individual to individual.
In DNA fingerprinting, enzymes are used to cut the DNA in the smaple found at the crime scence

DNA fingerprinting is a technique that takes advantage of repeated DNA sequences that do not code for proteins. It is a useful technique in forensic science.

A DNA fingerprint is 'taken' by removing the genetic material from a cell. This genetic material consists of DNA bases which are sorted into groups. The DNA bases are then cut and some radioactive nucleutides added. The radioactive DNA is then collected and is ready for analysis.
DNA fingerprinting is not as reliable as regular DNA profiling. Statistics show that about one out every 800,000 people have the same DNA fingerprint.
DNA coding is a science concept for fingerprinting
