Dna Technology

DNA TECHNOLOGY

How is DNA technology used in law enforcement? There are many different

ways it is used, but it is mostly used to solve crimes. Much

like deaths, rapes, or even big robberies. DNA is a way to identify a person by: blood, hair, skin, saliva etc... That is why when people are trying to

only investigators could pass into the area.While they are invetigating they are looking for any items that might have DNA on it from the killer.

Then they use DNA technologies to " discover" or trace the killer and to find who the victom is or was.

Restriction Fragment Length Polymorphism (RFLP) is a technique for analyzing the variable lengths of DNA fragments that result

from digesting a DNA sample with a special kind of enzyme.This enzyme is a restriction endonuclease which

cuts DNA at a specific sequence

pattern known as a restriction endonuclease recognition site. The presence or absence of certain
