What is the Human Genome Project-?
The Human Genome Project is an international effort to map and sequence all the DNA base pairs of the human genome. It's also an effort to identify the all the genes and the protein/trait that they code for in the human genome. ============================================== The Human Genome Project studies the human chromosomes to determines which genes are involved in what aspects of the human body reproduction, growth, functioning, and health intending to produce a map of the DNA structure, what it does, and how.
How many gens did scientist expect to identify during the human genome project?
In 2003, estimates from gene-prediction programs suggested there might be 24,500 or fewer protein-coding genes. The Ensembl genome-annotation system estimates them at 23,299.When analysis of the draft human genome sequence was published by the International Human Genome Sequencing Consortium on February 15, 2001, the paper estimated only about 30,000 to 40,000 protein-coding genes, much lower than previous estimates of about 100,000. This lower estimate came as a shock to many scientists because counting genes was viewed as a way of quantifying genetic complexity. With about 30,000, the human gene count would be only one-third greater than that of the simple roundworm C. elegans, which has about 20,000 genes.Studies since the publication of the draft genome sequence have generated widely different estimates. An analysis by scientists at Ohio State University suggested between 65,000 and 75,000 human genes, and another study published in Cell in August 2001 predicted a total of 42,000Although the completion of the Human Genome Project was celebrated in April 2003 and sequencing of the human chromosomes is essentially "finished," the exact number of genes encoded by the genome is still unknown. October 2004 findings from The International Human Genome Sequencing Consortium, led in the United States by the National Human Genome Research Institute (NHGRI) and the Department of Energy (DOE), reduce the estimated number of human protein-coding genes from 35,000 to only 20,000-25,000, a surprisingly low number for our species. Consortium researchers have confirmed the existence of 19,599 protein-coding genes in the human genome and identified another 2,188 DNA segments that are predicted to be protein-coding genes.In 2003, estimates from gene-prediction programs suggested there might be 24,500 or fewer protein-coding genes. The Ensembl genome-annotation system estimates them at 23,299.It could be years before a truly reliable gene count can be assessed. The reason for so much uncertainty is that predictions are derived from different computational methods and gene-finding programs. Some programs detect genes by looking for distinct patterns that define where a gene begins and ends ("ab initio" gene finding). Other programs look for genes by comparing segments of sequence with those of known genes and proteins (comparative gene finding). While ab initio gene finding tends to overestimate gene numbers by counting any segment that looks like a gene, comparative gene finding tends to underestimate since it is limited to recognizing only those genes similar to what scientists have seen before. Defining a gene is problematic because small genes can be difficult to detect, one gene can code for several protein products, some genes code only for RNA, two genes can overlap, and many other complications.Even with improved genome analysis, computation alone is simply not enough to generate an accurate gene number. Clearly, gene predictions will have to be verified by labor-intensive work in the laboratory before the scientific community can reach any real consensus.See the related link.
Do most of the complex phenotype we observe come from a single gene?
No. A phenotype is what we see. The Human Genome Project has revealed that there are probably about 20,000-25,000 protein coding genes. There are most likely thousands more that have not been identified.
