5094 annotated genes have been documented in David Ewing Duncan’s
genome, a new world record. His DNA has been read by three different
companies, who’ve collectively checked 1.7 million locations out of the
3 billion positions of his DNA. His report from SNPedia can be read
The record was documented on June 7, 2009 in San Francisco, California.
Mike Carioso, curator of SNPedia, was present to serve as the witness.
Michael Smith of Princeton University’s Rose Lab successfully
performed 147 yeast plasmid transformations by hand in a single sitting.
Each transformation was conducted in a microcentrifuge tube, and then
plated onto -URA glucose media.
