DNA Fingerprinting make very easy to identify to someone

DNA Fingerprinting
DNA profiling also called DNA fingerprinting, DNA testing, or DNA typing. DNA fingerprinting is a forensic technique used to identify individuals by characteristics of their DNA. A DNA profile is a small set of DNA variations that is very likely to be different in all unrelated individuals, thereby being as unique to individuals as are fingerprints. DNA profiling should not be confused with full genome sequencing.

While some fear the invasion of privacy contingent on DNA databases produced from DNA fingerprinting it is under able that the technique has had a positive impact in areas such as forensics, paternity testing and animal classification.

After studying at Oxford University, biochemist Alec Jeffrey’s (Birth Year: 1950) became a professor in 1977 at the University of Leicester where he worked on DNA variation and genetic evolution in families. He studied inheritance patterns of disease specifically in what are called “mini-satellites” or areas of great genetic variation that occur in the human DNA sequence outside of core genes.
In 1984, while studying mini-satellites in the DNA of seals, Jeffrey’s tested a probe made of DNA on samples from various different people using X-ray film. When he developed the film he saw what he described as a “complicated mess”. Upon closer examination, however, he realized that certain patterns occurred that varied greatly from person to person. The mini-satellite DNA pattern from each person was unique just like fingerprint.
Jeffrey’s quickly realized the implication of his discovery especially in the field of forensic science. He obtained patents in 1984 and published a series of papers in the journal Nature in 1985. The technique was first in a U.K. immigration dispute and in 1986 it was used in a chemical case in Leicestershire. DNA fingerprinting is now standard practice in criminal cases and newer techniques have automated the process to produced quick and reliable results.
