A brief history of DNA profiling and the breakthroughs that have made this possible. Biology - Cells And DNA - Learning Points. DNA is described as a 'blueprint' of an organism and is unique to all but identical twins. Since the 1960s, the development of DNA fingerprinting has enabled forensic scientists to identify suspects. In 1987, fragment length polymorphism was first used to successfully identify and convict a criminal. By 1997, the development of polymerase chain reaction meant that tiny samples of hair, blood and saliva could be used to recreate a criminal's DNA profile. A Twig Context Film. Reinforce and extend the learning required by the curriculum. Twig’s context films show abstract concepts in action in the real world.\n
