Article  The project exemplifies the power, necessity and success of large, integrated, cross-disciplinary efforts - so-called ‘big science’ - directed towards complex major objectives. 2009, 10: 355-386. Second-generation cyclic array sequencing platforms produce, in a single run, up to hundreds of millions of short reads (originally approximately 30 to 70 bases, now up to several hundred bases), which are typically mapped to a reference genome at highly redundant coverage [19]. 2008, 4: e1000201-10.1371/journal.pcbi.1000201. So virtually every argument initially posed by the opponents of the HGP turned out to be wrong. The primary goal of this project was to determine the order of all 3 billion bases in the entire human genome; this process is called sequencing. It was able to take advantage of economies of scale and the coordinated effort of an international consortium with a limited number of players, which rendered the endeavor vastly more efficient than would have been possible if the genome were sequenced on a gene-by-gene basis in small labs. The Human Genome Project (HGP), which began in 1990, was a massive international effort carried out by twenty research centers and universities in six countries. You can think of sequencing as assembling a puzzle. This 3-billion-dollar, 15-year program evolved considerably as genomics technologies improved. As a result, the genetic analysis of the UK Biobank data has essentially been crowdsourced to scientists all over the world. Science. 2002, 12: 996-1006. 10.1038/nature11247. The DNA must be broken into pieces prior to sequencing because these reactions can only read short DNA strands, typically less than 1000 bases. Nature. Human genome quiz.

It is also worth noting that one aspect that attracted governmental support to the HGP was its potential for economic benefits. It remains the world's largest collaborative biological project. LH receives support from NIH P01 NS041997; 1U54CA151819-01; and DOD awards W911NF-10-2-0111 and W81XWH-09-1-0107. The high-throughput nature of this sequencing may eventually lead to human genome costs of $100 or under. 10.1002/pmic.201100601. Science. 10.1038/nrg2841. 2012, 12: 2773-2783. The question as to what fraction of the thousands of GWAS hits are signal and what fraction are noise is a concern. Nat Methods. Using multiple approaches, many based on second-generation sequencing, the ENCODE Project Consortium has produced voluminous and valuable data related to the regulatory networks that govern the expression of genes [24]. This technology, now called ‘first-generation sequencing’, relied on gel electrophoresis to create sequencing ladders, and radioactive- or fluorescent-based labeling strategies to perform base calling [12]. These genomes provide insights into how diverse organisms from microbes to human are connected on the genealogical tree of life - clearly demonstrating that all of the species that exist today descended from a single ancestor [32]. The Human Genome Project made it possible to ask and address new types of scientific questions. These latter examples portend a revolution in blood diagnostics that will lead to early detection of disease, the ability to follow disease progression and responses to treatment, and the ability to stratify a disease type (for instance, breast cancer) into its different subtypes for proper impedance match against effective drugs [59]. Which regions of the genome appear to be resistant (or particularly susceptible) to mutation or highly susceptible to recombination? California Privacy Statement, It is made up of four types of smaller molecules, referred to as “bases”: adenine (A), thymine (T), cytosine (C), and guanine (G). Nat Genet. Springer Nature. The genome of an organism is the entire genetic material of that organism. 10.1038/nature06884. Nature. Venter’s initiative prompted government funding agencies to endorse production of a clone-based draft sequence for each chromosome, with the finishing to come in a subsequent phase. There are many levels of complexity in biology and medicine; big science projects are essential to tackle this complexity in a comprehensive and integrative manner [45].

Genovese G, Handsaker RE, Li H, Altemose N, Lindgren AM, Chambert K, Pasaniuk B, Price AL, Reich D, Morton CC, Pollak MR, Wilson JG, McCarroll SA: Using population admixture to help complete maps of the human genome. Initially, the HGP set out to determine a human genetic map, then a physical map of the human genome [10], and finally the sequence map. Then, they make lots of copies of the DNA in the sample and break those copies into many smaller, overlapping pieces (Figure 2). Article  By re-committing to data sharing, researchers can fulfil the long-delayed promise of the Human Genome Project. Cite this article. The order of bases, or the sequence, in each of those pieces can then be determined by a series of chemical reactions. Human Genome Sequencing Consortium: Finishing the euchromatic sequence of the human genome. Gene concept Abbott A: Neuroscience: solving the brain. Strikingly, we have learned from the HGP that there are no race-specific genes in humans [65–68]. http://www.ornl.gov/sci/techresources/Human_Genome/project/herac2.shtml, http://www.genomesonline.org/cgi-bin/GOLD/index.cgi?page_requested=Complete+Genome+Projects. 10.1038/321674a0.

For example, as yet at least 5% of the human genome has not been successfully sequenced or assembled for technical reasons that relate to eukaryotic islands being embedded in heterochromatic repeats, copy number variations, and unusually high or low GC content [69]. The Human Genome Project has transformed biology through its integrated big science approach to deciphering a reference human genome sequence along with the complete sequences of key model organisms. 10.1007/s00018-008-8432-4. Proteins - whether they act as signaling devices, molecular machines or structural components - constitute the cell-specific functionality of the parts list of an organism’s genome.

The Talking Glossary features more than 250 common genetic terms pronounced and explained in an easy-to-understand way by leading scientists and professionals at the National Human Genome Research Institute. This article is part of our SITN20 series, written to celebrate the 20th anniversary of SITN by commemorating the most notable scientific advances of the last two decades. 1993, 262: 43-46. Second, the HGP also led to the emergence of proteomics, a discipline focused on identifying and quantifying the proteins present in discrete biological compartments, such as a cellular organelle, an organ or the blood. As it turned out, the initial human genome reference sequence was deciphered using a 96-capillary (highly parallelized) version of first-generation technology. Part of However, there was controversy as to whether it was a good idea, with six of those assembled declaring themselves for the project, six against (and those against felt very strongly). D The human genome contains nucleotide sequences that all code for proteins Price ND, Edelman LB, Lee I, Yoo H, Hwang D, Carlson G, Galas DJ, Heath JR, Hood L: Systems biology and the emergence of systems medicine. Alternative approaches such as multiplexing [13] and sequencing by hybridization [14] were attempted but not effectively scaled up. Nat Genet. 2001, 285: 540-544. by Rebecca Fine Data produced by both projects have supported smaller-scale clinical genome-wide association studies (GWAS), which correlate specific genetic variants with disease risk of varying statistical significance based on case–control comparisons. 2004, 431: 931-945. Although it represented an advance in understanding the human genome and its complexity, many questions remained unanswered. First, let’s talk a little bit about terminology. 2010, 11: 685-696. Human Proteome Project. PLoS Biol. 2002, Bethesda: National Center for Biotechnology Information. We predict that individual genome sequences will soon play a larger role in medical practice. The Human Genome Project has inspired subsequent large-scale data acquisition initiatives such as the International HapMap Project, 1000 Genomes, and The Cancer Genome Atlas, as well as the recently announced Human Brain Project and the emerging Human Proteome Project. 1986, 321: 674-679. Thus, single-molecule analyses should be able to identify all the epigenetic marks on DNA.

Nat Rev Genet. In the first years of GWAS, however, it became apparent that matters would not be so simple: the findings suggested that a very large number of genes – for some traits, easily into the hundreds or perhaps even thousands – might have effects on a given disease. 10.1073/pnas.88.22.10089. Mapping would eventually reveal the position and spacing of the then predicted one hundred thousand genes in each of the human body's cells; sequencing would determine the order of the four base pairs—the A (adenine), T (thymine), G (guanine), and C (cytosine) nucleotides—that compose the DNA molecule. The Human Genome Project (HGP) was initiated in 1990 and completed in 2003. Hence, knowing how the information encoded by disease-perturbed networks changes provides insights into disease mechanisms, new approaches to diagnosis and new strategies for therapeutics [58, 59]. It established an open approach to data sharing and open-source software, thereby making the data resulting from the project accessible to all. The Human Genome Project has transformed biology through its integrated big science approach to deciphering a reference human genome sequence along with the complete sequences of key model organisms. This would be a drastic mistake. 2007, 5: e254-10.1371/journal.pbio.0050254. Cooke-Degan RM: The Gene Wars: Science, Politics and the Human Genome. The Human Genome Project (HGP), which began in 1990, was a massive international effort carried out by twenty research centers and universities in six countries. Church G, Kieffer-Higgins S: Multiplex DNA sequencing. The parts list has been essential for the emergence of ‘systems biology’, which has transformed our approaches to biology and medicine [21, 22]. Genome Res. The long reads of third-generation sequencing will allow for the de novo assembly of human (and other) genomes, and hence delineate all of the individually unique variability: nucleotide substitutions, indels, and structural variations. Commencement Address. Here we present a draft genome sequence of the common chimpanzee (Pan troglodytes). The HGP challenged biologists to consider the social implications of their research. In the wake of the HGP there are further valuable biological resource-generating projects and analyses of biological complexity that require a big science approach, including the HapMap Project to catalogue human genetic variation [47, 48], the ENCODE project, the Human Proteome Project (described below) and the European Commission’s Human Brain Project, as well as another brain-mapping project recently announced by President Obama [49]. Nature. 2010, 10: 1150-1159. Understanding Our Genetic Inheritance. Each participant also provides a veritable treasure trove of health data, ranging from basic information such as height and weight to dietary questionnaires and disease status (a total of over 2,400 traits!). Google Scholar. 2001, 409: 860-921. The interesting question is how long it will take to make third-generation sequencing a mature technology. Similarly to the HGP, significant returns on investment will be possible for other big science projects that are now under consideration if they are done properly. Editorial: The call of the human proteome. This will be even more critical in medicine, as scientists need access to the data cloud available from each individual human to mine for the predictive medicine of the future - an effort that could transform the health of our children and grandchildren [44]. Cell Mol Life Sci. It is increasingly clear that these epigenetic modifications play important roles in gene expression [76]. Elayne Fivenson is a second-year PhD student in the Biological and Biomedical Sciences program at Harvard Medical School, where she is studying the genetics and biochemistry of the bacterial cell envelope. At the inception of the HGP in the early 1990s, there was optimism that the then-prevailing sequencing technology would be replaced. The HGP also fostered the development of mathematical, computational and statistical tools for handling all the data it generated. In addition to providing a foundation for subsequent studies in human genomic variation, the reference sequence has proven essential for the development and subsequent widespread use of second-generation sequencing technologies, which began in the mid-2000s. CAS  Rebecca Fine is a fifth-year graduate student in the Biological and Biomedical Sciences PhD program at Harvard Medical School, where she studies human genetics. Nature. Fast-forward sixteen years from the completion of the HGP, and genomics has moved at a speed no one could have predicted. The completion of the human genome project (HGP) is an example of newsworthy science that has the potential to have major effects on our society today. Integrating these data allows the creation of models that are predictive and actionable for particular types of organisms and individual patients.

A National Academy of Science committee report endorsed the project in 1988 [8] and the tide of opinion turned: in 1990, the program was initiated, with the finished sequence published in 2004 ahead of schedule and under budget [9]. Genome Res. Fifth, the HGP, as conceived and implemented, was the first example of ‘big science’ in biology, and it clearly demonstrated both the power and the necessity of this approach for dealing with its integrated biological and technological aims. Rapid advances in the science of genetics and its applications have presented new and complex ethical and policy issues for individuals and society.

Experiments that were inconceivable 20 years ago are now routine, thanks to the proliferation of academic and commercial wet lab and bioinformatics resources geared towards facilitating research. This makes it extremely difficult to precisely identify the insertion-deletion and structural variations in the human genome, both for our species as a whole and for any single individual.
