If so, where? What type of degree does it take? Is it boring? Do you get to go to Crime Scenes and do fingerprinting? What company do you work for?

As part of the Human Genome Project, researchers are determining the nucleotide sequences of human genes and identifying the proteins coded by the genes. Labs on the U.S. national Institutes of Health, for example, have worked out thousands of sequences, and similar anaylysis is being carried out by many private companies. Knowing the neucleotide sequence of a gene and identifying its product can be useful;this information might be used to treat genetic defects or droduce life-saving medicines. The U.S. law allows the first person or research group to isolate a pure protein or a gene to patent it, whether or not a practical use for the discovery has been demonstarted. THe NIH and biotechnology companies have applied for patents on their discoveries. What are the purposes of a patent? How might the public benefit? What kinds of negative impacts might result from patenting genes? Do you think individuals and companies should be able to patent genes and gene products? why or why not?

recent bird die offs have given rise to my querie with the avian flu being such a worry to health officials from a human standpoint little attention has been given to the impact that this or other natural cause quickly reduced the number of birds of all species worldwide to say less than 10% of there current numbers. So my question is what impact would a near extinction or drastic reduction in numbers of birds of all species worldwide have on the ecosystem
