Dr. Ellingtons's objections to the genome project seem to me to fall into 3 categories: financial, systematic, and scientific. 1) Financial -- the genome project is cutting into NIH funding for other projects and molecular evolution projects are difficult to get funding for. While there is some truth to this, I think the bulk of the funding for the genome program is new money. NIH's funding problems can be traced to a number of sources, including the large increase in the number of continuing grants funded several years ago, and a substantial increase in the number of researchers competing for grants. It seems to me that it is very unlikely that cancellation of the genome program would result in the transfer of the allocated funds to NIH general program. Congress would probably see a "better" use for them (congressional salaries perhaps, certainly not deficit reduction). There are also a number of projects funded previously by the NIH which are now funded by genome project funding, thereby freeing up this money for non-genome projects. Or another way of looking at it: some of the genome project money way already being spent on the same projects even before the prject officially existed. 2) Systematic -- the information resulting form the genome project is available by other means and few if any new lines of research will be opened up. To apply this standard to the genome project seems unfair. Few if any grants describe a problem that can't be tackled by other means. Most merely continue an existing line of inquiry and do not open up new ones. 3) Scientific - too little is known about human genes; the genetic map is too poor to justify sequencing the genome, besides most of the DNA is "junk" anyway. Furthermore the project is anthropocentric, ignoring the genomes of species which are much better characterized genetically. Many, if not the majority, of genes can be identified and the identity of the protein product determined by comparison to known genes from other organisms. It is not unreasonable to expect that by the time actual genome sequence is available that most genes will be able to be identified in this way. My understanding of the current project is the large parts, if not all, of the sequences of the following model systems will be sequenced in the course of the genome project: E. coli, yeast, fly, nematode, and mouse. These include some of the most well characterized gneetic systems. Perhaps the project should have been called the "lots of genomes project", but this would have been difficult to sell to congress. Although we do not understand the function of much of the non-coding DNA, it is really premature to call it "junk". Only a few years ago, the self-splicing introns that Dr. Ellington find interesting would have also been characterized as junk. -------------------- As to whether the resulting information will be useful, I admit that we won't really know until we have a good piece of it. The project is speculative, as is a lot of good science. One of my main worries is that it is being heavily oversold to congress as a panacaea for human disease. This may ultimately result in a painful congressional backlash. The actual sequencing of genomes is still five years or more down the road and we will be in a much better position to judge the value of the project in a few years. In the meantime, the five year goals of the project appear to me to be very justifiable and of wide general use. My synopsis gleaned from the U.S. Human Genome Project: FY 1991-1995 (DOE/ER-0452P) report. 1) Complete a fully connected human genetic map with markers 2-5 centimorgans apart, each associated with an STS. 2) Assemble STS maps of all human chromosomes with markers at at 100kb intervals. Generate overlapping clones with continuity over 2mb. 3) improve sequencing technology to allow sequencing at a cost of $ 0.50/bp. 4) prepare a genetic map of the mouse genome based on DNA markers and physically map one or two chromosomes. 5) develop effective software and database designs to deal with mapping and sequence data. 6) support research training of up to 600 pre- and post-doctoral trainees. The technique of ridiculing a project (by comparison to phlogiston or N-Rays) would seem to indicate a lack of real arguments. Creationists often ridicule evolution with the same "ohmigosh, it's unimaginable" in the course of proving that evolution is impossible. I repeat -- many reputable scientists see some value in the genome project -- not all of them are fools. And no, I do not feel that I need to list them; Most of us know who they are, anyone can find out by reading a little. Michael Gribskov gribskov@ncifcrf.gov
