  Since the gaps in the sequence were unlikely to contain genes, and only genes as functional segments of DNA have potential commercial value, Celera was happy to move on and leave these gaps for the HGP scientists to fill in. Celera was faced with deciding what sort of company it would be: sequences from three different mouse strains were added to help attract subscribers to its database, and a brief foray was made into proteomics, but Venter resigned as CEO in January 2002 with the company's decision to focus on drug discovery rather than information (Davies 2002). Despite being timed to coincide with celebrations of the 50th anniversary of the Watson-Crick discovery of the double-helical structure of DNA, there was less fanfare surrounding the official date of completion of the HGP in April 2003, two years earlier than had been anticipated at the time of its official launch in October 1990, and several months earlier than called for in the most recent five-year plan. Americans had terrorism and war on their minds. In the end, sequencing—the third phase of the publicly-funded project—was carried out at 16 centers in six countries by divvying up among them sections of chromosomes for sequencing. 85 percent of the sequencing, however, was done at the five major sequencing centers (Baylor, Washington University, Whitehead-MIT, Sanger Center, and DOE's JGI), with the Sanger Centre responsible for nearly one-third. The cost was lower than anticipated, with $2.7 billion spent by U.S. agencies and £150 million spent by Wellcome Trust. The “finished” reference DNA sequence for Homo sapiens—all 3.1 billion nucleotide bases—is publicly accessible on the Internet  (NCBI Human Genome Resources). If the As, Ts, Cs, and Gs of the genome sequence were printed in standard type, they would fill 75,490 pages of the New York Times (Wade  2003).[12]
