Genome Project: C'est magnifique, mais ce n'est pas ...
The publicly funded International Human Genome Project (HGP) consortium using the "hierarchical shotgun approach," and Dr. Craig Venter's Celera Corporation using the "whole-genome shotgun approach" (WGS) achieved the nearly complete joining of all the sequence fragments of the human genome into one. The tentative identification of some 40,000 genes was announced in the New York Times of 11th February 2001:
It is for the reader to ponder Venter's mental exhaustion. His organizational and marketing skill are hardly to be doubted. But if those seeking to understand the genome through bioinformatic and evolutionary analysis had had just one fraction of a percent of the funds available to the Consortium and Celera, they might have already achieved the transformation of mere data (let us not dignify it as "knowledge") into understanding? Sydney Brenner pointed out:
Along similar lines Margaret Somerville commented:
And let us not pretend that we actually needed the sequence of the entire human genome in order to complete our understanding. Just as one does not need access to an entire dictionary if one wants to understand how a dictionary works, so one does not need access to an entire genome to find out how genomes work. And for most of us an entire dictionary is redundant. Our needs are highly selective. Few of us want to look up the word "and." Many might want to look up the word "esoteric."
Similarly, techniques developed in the early 1980s (e.g. Forsdyke 1985) allow us to selectively access genes likely to be of importance (Click Here). We now have an excess of human genomic sequences, not because they might reveal "long-sought secrets of human development, physiology and medicine," but because the project is highly marketable, and because of patent possibilities. Those who really want to understand the human genome know that it is far more important to sequence comparable segments of non-human genomes.

Sir--The overtaking of publicly funded research teams by Celera Genomics in its completion of the sequencing of the human genome, to which you refer in your Jan 13 editorial,1 smacks somewhat of the Sputnik episode.
The United States of Soviet Russia scaled up the payload of their rocket and put a man into space before the USA, but did not make parallel progress in the other technologies required to capitalise on this advance. Craig Venter, the chief executive officer of Celera, has stated that understanding the genome may help resolve previously unanswerable questions.2 But Celera has merely made available the full text of the genome a little sooner than we might otherwise have had it. Those of us working to understand the genome3 no more need the full text of the genome than you would need the full text of a dictionary if you were trying to understand how a dictionary works.
You state that, courtesy of Celera, the entire sequence will be available free of charge;1 a Celera spokesman has declared that academic users will have to pay US$7000 per year.4 That the beneficence, and perhaps the integrity, of Celera might not be relied on, was suggested by a full-page colour advertisement in Canada's leading newspaper. This advertisement, in large capital letters, declared "The skeptics were right when they said Craig Venter would never crack the human genetic code on schedule. He was two years early".
We smiled when Al Gore told us he had invented the Internet, and he quickly apologised and expressed remorse. Yet, here is the chief executive officer of Celera claiming to have cracked the genetic code--a feat achieved in the 1960s, and for which Nobel prizes were awarded in 1968. My protest in a letter to the newspaper on Jan 15,5 which was forwarded to Venter's corporate sponsors, was answered by repeats of the advertisement on Jan 16, 22, and 25.

|Let the Cobbler Stick to his Last|
The human sequence was deposited in various electronic databases. However, the sequencers, having delivered up the human genome, had to report the fact in the scientific literature. Their task was to describe any novel aspects of the methodology, compare the two sequence approaches, and outline the general features of the genome. That was all. To his credit Venter expressed some diffidence (see above). However, the temptation to go beyond their brief was too great. The speculations of the genome amateurs were soundly quashed by the great "genomographer" of our times, Georgio Bernardi, in a two part article in Gene (2001; 276, 3-13) euphemistically entitled "misunderstandings."

Did Celera independently sequence the human genome?
this question the answer seems to be negative. In March 2002 (Proc.
Natl. Acad. Sci. USA 99,
members of the publicly funded consortium who had used the hierarchical
shotgun approach pointed out that:
The authors concluded that the Celera approach:
The Celera group considered that "this conclusion is based on incorrect assumptions and flawed reasoning." (2002; PNAS 99, 4145-46.
