Huge accomplishment came in 2003, when the entire human genome was sequenced. That amounts to 3.5 billion data points–as one team member put it, giving nearly three copies of the whole genome for each person on earth. Genome sequence in theory meant that we were sitting on the brink of enlightenment for human biology, disease, and inheritance. By 2007, when the 21st Century Human Genome Project, funded with over $100 million from RIKEN and their friends at DNA Chip Research, succeeded in producing an advanced map of genetic variation—covering all kinds of animals, plants, 11 races including human beings…… Looking back on it now from 40 or so years later. Perhaps this last stage of the Human Genome Project will be the most successful of all, because it should provide methods to edit and release new genes into cells in almost any species–including humans!
The Human Genome: An Instruction Manual for Our Lives
The original goal of the Human Genome Project was to identify and map each gene in human DNA. It was supposed to be a kind of general-purpose data domain for medicine. Every scientist could have access to it, and on their own territory in such fields as medical, genetic and biotechnological research they might find what they wanted from this singular directory file. In 2003, scientists sequenced the human genome. They identified some 20,000-25,000 protein-coding genes and more than 98% of human chromosomes’ base pairs that make up DNA.
At its essence, the genome is a biological instruction book. It shows us how to build living organisms; how those organisms work and even about the maximum life span for living things.
Personalizing Medicine
One of the most thrilling prospects of the Human Genome Project was personalized medicine. Medical practitioners could tailor treatments and therapies to fit the needs of individual patients by knowing their genetic predisposition. In this way, efficacy in medicine could be raised as side effects are reduced or eliminated.
Word has it that something wondrous has happened here during the last two decades. Now genetic testing is coming closer to everyday medical practice and will thus enable doctors to employ a person’s individual genetic profile as an early warning system for the likelihood of their suffering from certain diseases. This year has also seen the clinical maturation of the testing field. A number of tests for detection diseases that involve mutations in genes, such as: breast cancer and BRCA1、BRCA2and cystic fibrosis have already become routine in many hospital medical practices. This can achieve early detection, identifying risks sooner so diseases are no longer so serious or allows these potentially lethal conditions to be dealt with It is also driven by pharmacogenomics–the scientific study of how genes influence someone’s response to drugs. In fact, it has meant that doctors are able to tell which drugs will work best in each person depending on their genetic makeup.
Genetic testing is a harbinger of new tools that will combine DNA technology and information technology, which will ultimately support individualized medical care. But the prospect of completely personalized medicine is still work in progress. Despite the rapid development of gene-based therapies–such as gene editing and precision oncology that have made great strides recently–there are still problems. First, gene-environment interactions are complex. Second, there is the role of epigenetics (i.e., changes in gene expression not directly related to changes in the DNA sequence itself); and finally, in addition to the complexity of human genomes as mentioned earlier there is diversity among genomes.
The rise of CRISPR and Gene Editing
One of the most potentially revolutionary initiatives since the Human Genome Project was probably CRISPR-Cas9 technology. This gene-editing kit has opened up a new phase in medical technology. It has been used to change the sequence of DNA in cells that are in an organism including human beings. In other words, with this technology people who might previously have been declared incurable now become instead themselves a cure for their disease. For example, CRISPR is already showing promise in such perennial genetic diseases as sickle-cell anemia, muscular dystrophy and certain types of inherited blindness. In 2020, the first CRISPR trials for patients with genetic diseases produced results that were both successful and early. At the same time, discussions continue about the ethical side of gene editing. Whether it involved germline or somatic cells, i.e. if it affected the developing embryo’s gene composition, these debates are still fiercely contested among experts in science and society alike.
Disease Understanding and Treatment We have also learned much about disease genetics in greater depth through the Human Genome Project. Our genes are now mapped. Scientists may thus, for example, find the abnormal genetic information that is likely responsible for heart disease and diabetes in the vast majority of cases. However, with rare inherited diseases such as Huntington’s chorea and myogenic dystrophy they may have to search a little harder and look longer in order to discover its existence.
In cancer research, the ability to sequence tumors’ genomes meant that specific mutations driving cancer could be identified. As a result, therapies targeting those mutations were developed, a great advance on the former “one size fits all” approach to treating cancer.
In addition, the human genome has also speeded up genomics approaches, for instance allowing non-coding DNA research. These areas constitute a vast portion of the genome that was once regarded as ‘junk’. It transpires, however, that these non-coding areas play something rather critical in regulating human gene processes and that changes therein may be the cause of diseases such as cancer polymerase chain reaction best site. The findings widened our understanding of the molecular map fitness landscape, providing new regions for further study.
Deciphering the Secrets of Human Evolution
In addition, genomics has come to reveal yet another aspect of humankind: its diversity. Of the 99.9% identical, therefore, it makes all the difference in whether a Chinese person is brown-skinned and brown-eyed, tall or fair-skinned blue eyed short–to a large extent we will dutifully incur variation. Further rearing against these settings of men women and children how toward dinner as opposed brunch.
Interpretation and Privacy of Data
On the other hand, after the human genome is completely sequenced and we have smoothed out all those glitches that would bar our way then we must still face with ir control for many other mountains of information arising from this vast project. The human genome consists of billions of base pairs, the roles of specific genes can be understood only with supercomputing capacity plus very sophisticated algorithms for mutations or natural variations. Furthermore not all gene variations serve any known function making it difficult to draw any fixed conclusions.
So naturally privacy. New born baby, is it correctly spelling a name of intelligence? Patients”
Once genomic knowledge is finally integrated into healthcare, concomitant with this trend comes the development of security problems and privacy issues. In the post-genomic age medicine will also become molecular: for information of this sort is highly personal and potentially raises matters that may be embarrassing to individuals about their health and background.
Looking Ahead
Reduced costs and greater public understanding have enlarged the molecular biology landscape for everyone, heralding in what can at best be described as molecular medicine where genomic information is routinely used to diagnose disease. Two examples of such software abound in health-care market leader Yizhi Miyun and the China Human Medical Genome Project by James Watson, but they are just two specific instances. This puts equity ahead of efficiency, seeking cheap and quick sequencing methods that offer less protection than individually-performed ones.
In the future, AI will become an increasingly important when object- and subject-oriented IT merge in life sciences. This implies that intelligence is driven by information rather than driven through biology but no less capable of being copied. Moreover, AI is already embedded deep into today’s clinical wards. It plays a significant role in analyzing complicated genetic data to predict disease risks and create new drugs.
In the future, I think we will be able to obtain more information from genetics-interactions with the environment. The revolutionary discipline of ‘epigenetics’ studies environmental influences on gene activities and is likely to provide an entirely new perspective for major diseases like cancer, obesity as now treated as diverse outbreaks among somebody’s children (i.e., each individual occurrence carrying its separate category name) and mental illness.
Conclusion
Twenty years following the completion of the Human Genome Project we now stand on edge of an entirely new era in medical science. It is true that mapping of human genes represented an important new milestone, but this was only the beginning. As the work of Human Genome Project shapes our view for evermore of biology, medicine and inferences on human evolution. We all do personalized medicine and gene therapy for this Experiments have shown that it produces results comparable to world-class clinics with only a fraction of the equipment cost for some services. projects–interestingly enough CPG companies aren’t getting into these much at all. They Looking ahead, the next phase of genomics has the potential to fundamentally change how we think about medicine and health –maybe also human identity.
