Virus and spyware definitions are files that act like an encyclopedia of known malicious software, including viruses, spyware, and other potentially unwanted software.
Highly accurate DNA parental testing became available in the 1980s with the development of RFLP. In the 1990s, PCR, developed in 1983, became the standard method for DNA parental testing. A simpler, faster, and more accurate method of testing than RFLP, it has an exclusion rate of 99.99% or higher.
In May 1986 Mullis presented PCR at the Cold Spring Harbor Symposium, and published a modified version of his original 'idea' manuscript much later. The first non-Cetus report using PCR was submitted on September 5, 1986, indicating how quickly other laboratories began implementing the technique.
