This version, which is available to the public, provides nearly all the information needed to do research using the whole genome. The difference between the draft and finished versions is defined by coverage, the number of gaps and the error rate. The draft sequence covered 90 percent of the genome at an error rate of one in 1, base pairs, but there were more than , gaps and only 28 percent of the genome had reached the finished standard.
In the April version, there are less than gaps and 99 percent of the genome is finished with an accuracy rate of less than one error every 10, base pairs.
The differences between the two versions are significant for scientists using the sequence to conduct research. Every part of the genome sequenced by the Human Genome Project was made public immediately, and new information about the genome is posted almost every day in freely accessible databases or published in scientific journals which may or may not be freely available to the public.
The Supreme Court ruled in that naturally occurring human genes are not an invention and therefore cannot be patented. However, private companies can apply for patents on edited or synthetic genes, which have been altered significantly from their natural versions to count as a new, patentable, product. The Human Genome Project could not have been completed s quickly and as effectively without the strong participation of international institutions.
However, almost all of the actual sequencing of the genome was conducted at numerous universities and research centers throughout the United States, the United Kingdom, France, Germany, Japan and China. In , Congress established funding for the Human Genome Project and set a target completion date of Additionally, the project was completed more than two years ahead of schedule.
It is also important to consider that the Human Genome Project will likely pay for itself many times over on an economic basis - if one considers that genome-based research will play an important role in seeding biotechnology and drug development industries, not to mention improvements in human health.
Since the beginning of the Human Genome Project, it has been clear that expanding our knowledge of the genome would have a profound impact on individuals and society. The leaders of the Human Genome Project recognized that it would be important to address a wide range of ethical and social issues related to the acquisition and use of genomic information, in order to balance the potential risks and benefits of incorporating this new knowledge into research and clinical care.
The United States Congress mandates that no less than five percent of the annual NHGRI budget is dedicated to studying the ethical, legal and social implications of human genome research, as well as recommending policy solutions and stimulating public discussion.
The ELSI program at NHGRI, which is unprecedented in biomedical science in terms of scope and level of priority, provides an effective basis from which to assess the implications of genome research.
Among these are major changes to the way investigators and institutional review boards handle the consent process for genomics studies. The ELSI program has been effective in promoting dialogue about the implications of genomics, and shaping the culture around the approach to genomics in research, medical, and community settings.
Having the essentially complete sequence of the human genome is similar to having all the pages of a manual needed to make the human body. The challenge to researchers and scientists now is to determine how to read the contents of all these pages and then understand how the parts work together and to discover the genetic basis for health and the pathology of human disease. Thousands of scientists all over the world worked for over ten years to read every instruction inside every gene of a group of volunteers and put together a picture of the average human genome.
They discovered we have around 20, genes in almost every cell in our bodies. These small differences contribute to our unique features. Our new understanding of the human genome is leading to many advances in how we treat illness and disease. How about Personalised Medicine? Soon everyone could have their genes read. A doctor might use the information to give you specific medicines, tailored for your genes.
Some people respond really well to a medicine, some may not respond at all, and others experience bad side effects. Scientists are learning how differences in your genes affect your reaction to medicines. These genetic differences will help doctors predict which medicines will work for you, so they can prescribe personalised treatments. Genes can tell us a lot about how to treat and prevent illness, but that's not all Studying the genes of people around the world can also tell us about our ancestors.
What about the genetics of big populations? Studying your genes can reveal where your ancestors came from. Evidence suggests that humans originally came from Africa and spread out across the rest of the world. As humans migrated around the world, tiny variations in their genes developed.
Over time, this happens naturally to help humans survive change. These variants were then passed down through generations. Scientists look at the genes of different populations of people around the world to spot these variations, trace them back though time, and map how our ancestors moved around. Genetics is exciting, here's where to find out more.

It is capable of reproducing itself exactly at each cell division. Each DNA molecule contains many genes; the human genome is estimated to contain approximately 80,, genes. The 3 billion base pairs of DNA in the human genome are organized into 23 distinct, physically separate microscopic units called chromosomes.
All genes are arranged linearly along the chromosomes. As others have noted, just because a given DNA sequence binds protein or is associated with some chemical modification does not necessarily mean that it is functional or serves a useful role. Many protein binding events are random and inconsequential. All of these concerns are certainly justified, and, in fact, the conversation surrounding the project demonstrates precisely how science is supposed to work.
It will most likely take years to fully understand how ENCODE has helped the scientific community, but nevertheless, this project has highlighted how important it is to study the genome as a whole, not only to understand why we have so much non-coding DNA within each and every cell, but also to inform us on topics that are relevant to the majority of people, notably how rare or multiple genetic mutations lead to the development of disease.

Skip to content Of the trillions of cells that compose our body, from neurons that relay signals throughout the brain to immune cells that help defend our bodies from constant external assault, almost every one contains the same 3 billion DNA base pairs that make up the human genome — the entirety of our genetic material.
Studying the Genome as a Whole So how do we start to understand the genome as a whole?
