What do restriction enzymes in DNA fingerprinting indicate?

Restriction enzymes are a special class of enzymes that can cut the DNA into fragments at specific locations called restriction sites. This is a defense mechanism employed by bacteria for protection against viral DNA or genetic code. read more

While using the restriction enzymes to cut up a person's DNA is an integral part of the process, scientists need to use one more technique to analyze the small fragments of DNA. Using a process known as gel electrophoresis, scientists can place the DNA samples into an agarose gel and run a current through the DNA samples. read more
