DNA polymerase (blue) makes many copies of DNA (red) in a cycle of the polymerase chain reaction (PCR).
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 explains how the polymerase chain reaction (PCR) was named.
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.
The cycles of the polymerase chain reaction (PCR).
The DNA sequencing method developed by Fred Sanger forms the basis of automated "cycle" sequencing reactions today.
This method uses homologous recombination to disable a gene of interest to produce a genetic knockout.
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.
