![]() They've also charted some plant and disease genomes. Scientists have mapped many animal genomes, among them that of the chimpanzee, mouse, rat, fruit fly, roundworm and puffer fish. Image courtesy Lawrence Livermore National Laboratory Some of these projects, such as mapping the mouse genome, were included in the original Human Genome Project and can tell us about our evolution and DNA. What was the goal of the human genome project code#Also, genes appear to grab genetic code from other DNA segments.īefore we look closely at heredity and genes, let's stop to consider what scientists have learned about animal and other genomes. We now know that some multitasking genes make more than one protein in fact, the average gene may make three proteins. Scientists have also reassessed previous assumptions, such as the idea that genes are self-contained, discrete pieces of DNA with defined roles. In addition, the HGP has helped to narrow the range of possible genes and to isolate certain candidates as contributing to specific diseases. But recent HGP estimates lowered that number to a more modest range of 20,000 to 25,000. Only a few years before the completion of the HGP, popular predictions stated that humans had up to 100,000 genes. ![]() Theoretically, with the main goals achieved, the project is finished. ![]() A "final" batch of results was published in 2006, but data produced by the HGP are continually examined, analyzed and occasionally revised. Department of Energy, the project was completed ahead of schedule in 2003. Run by the National Institutes of Health and the U.S. Sequencing genomes of the mouse and four other "model organisms".Charting variations across human genomes. ![]()
