These profiles can be referred to as “DNA Fingerprints” because, just as normal fingerprints, DNA profiles are unique to each individual. In 1985, Dr. Alec Jeffreys figured out that when DNA is cut with restriction enzymes, some DNA fragments are longer than others. The sizes of the fragments depend on the numbers of repeated DNA sequences. The variations come from people having different numbers of repeated DNA sequences. If we were to compare the DNA sequences of the evidence to all of the suspects associated with the case, we may find a match and determine who the criminal is. So, if DNA is used this way, DNA can be used to solve criminal cases. In his experiments, Jeffreys attached radioactive probes to dissimilar parts of DNA. When the images were developed, a series of black and gray bands showed that each person had his/her own unique profile. Bands of twins were the same, and bands of children were a combination of their parents. The difference reproductive cloning and therapeutic cloning is that reproductive cloning is creating a full living copy of an organism. Therapeutic cloning is the same procedure as cloning, but
