The letter called for an international meeting of the scientific community to “deal with the potential biohazards of recombinant DNA molecules.”

The process became popularly known as recombinant DNA.

In 1971, he was already a well-known researcher at Stanford University when he oversaw the artificial introduction of DNA from one virus into another, creating the first recombinant DNA, or rDNA.

"There is serious concern that some of these artificial recombinant DNA molecules could prove biologically hazardous," a panel of prominent scientists, chaired by Berg, wrote in Science in 1974.
