DNA Sequencing Technologies Key to the Human Genome Project

From the beginning, the Human Genome Project develops mainly on two main principles (International Human Genome Sequencing Consortium, 2001). First of all, welcome cooperators from all countries to work across borders, to understand the molecular heritage we share and to build comprehensive efforts to benefit from various approaches. The ultimate gathering of researchers by public funds is known as the International Human Genome Sequencing Consortium (IHGSC). Second, in this project all human genome sequence information is required to be freely available within 24 hours after assembly. The principle of this creation guarantees unlimited access by academic and industry scientists and provides researchers with a means for quick and innovative discovery. At any time, to support these efforts, about 200 laboratories in the United States are funded by the National Institutes of Health or the US Department of Energy. Furthermore, at the time of completion, more than 18 countries around the world contributed to the human genome project.
As the Human Genome Project develops around two important principles, it also starts with two initial targets. (1) Generation of genetic and physical maps of human and mouse genomes, and by this manipulation a larger, more complex human genome was sequenced (IHGSC, 2001). Once yeast and worm efforts are proved successful, sequencing of the human genome is done with full capacity.
By the 1990's, scientists began to consider new radical projects, thanks to the significant advances in DNA sequencing technology over the past several decades. This project is aimed at determining the sequence of the entire human genome and establishing the baseline human DNA sequence. If researchers can do this, you can understand how human DNA differs from baseline and how it affects the difference. It also makes it possible to better characterize the information encoded in our gene - even the number of genes we have at the beginning -. This radical project, the Human Genome Project, was officially launched in 1990.
During genome wide sequencing, researchers collect DNA samples and then determine the identity of 3 billion nucleotides constituting the human genome. The first human genome was completed in 2003 as part of the Human Genome Project officially launched in 1990. Today, sequencing techniques are more efficient and the human genome can be classified in less than $ 10,000 in a few days. The first human genome took $ 2.7 billion. Today, most genetic tests focus on one or more genes, not the entire genome. However, as the cost of genomic sequencing declines, more people are looking for this option. Physicians can examine the entire genome and see how specific treatments for the disease are affected by the individual's inherent genetics. For example, a doctor can choose to see genes related to drug metabolism in determining the dose. In the future, with the genome wide sequence, everyone will be able to make individual treatment plans.
DNA sequencing techniques allow researchers to determine the sequence of bases in a DNA sequence. This technique can be used to determine the order of bases in genes, chromosomes or whole genomes. According to the National Human Genome Research Institute, in 2000, researchers completed the first complete sequence of the human genome. Individual DNA contains information on its heritage and may reveal whether there is a risk of developing a specific disease. Several reasons to use DNA testing or genetic testing, such as diagnosing genetic diseases, determining whether a genetic mutation inherited by a child is a carrier or not, checking for the risk of a hereditary disease, etc. There is. For example, mutations in the BRCA1 and BRCA2 genes are known to increase the risk of breast and ovarian cancer, and analysis of these genes in genetic testing can reveal whether a person has these mutations I can do it.
