Image of Kary Mullis. In 1985, Kary Mullis invented the polymerase chain reaction (PCR), a method of amplifying or producing many copies of a specific piece of DNA. The revelation came to this eccentric character on a drive in northern California.
Polymerase chain reaction (PCR) enables researchers to produce millions of copies of a specific DNA sequence in approximately two hours. This automated process bypasses the need to use bacteria for amplifying DNA.
Kary Mullis talks about his discovery of the polymerase chain reaction (PCR), a process that allows chemists to produce many copies of a specific fragment of DNA.
James Watson describes sequencing the human genome using markers and BACs, and Craig Venter explains using cDNA libraries, ESTs, and shotgun sequencing.
