Date “Nova – Cracking Your Genetic Code”: the Summary
The PBS documentary “Nova – Cracking Your Genetic Code” tells about the genome sequencing technology: its current possibilities, advantages, disadvantages and future potential. The system became cheaper, faster and more available since the first human genome was fully sequenced in 2000. Modern companies use the technology to provide clients with the information about their genes and impacts they can have on owners’ health. Hospitals can provide more accurate diagnosis and personalized treatments with the aid of the genome sequencing. The video shows several examples of these benefits. But it mentions concerns about the quality of services, risks of exaggerated

It helps medics to find a direct genetic cause of the patient’s condition and target it with pharmaceutical or other therapies. The technology is used for the identification of DNA sequences that increase risks of current diseases and disorders; with this information carriers can start to make efforts to prevent them before the development of the problem. The video mentioned 200 actionable genes, structures that have direct links with a specific condition. Knowing about their presence, people have a chance to bring in preventive measures like taking anticoagulants in the case of identification of a thrombogenic gene. The technology led to the significant improvement of diagnostics and personalized treatments. It helped to find a rare, life-threatening mutation in case of Beery twins and assign a drug to a girl (Alexis) that returned her to a normal life. In the case of cancer genome sequencing led to the development of genetic drags, which target essential tumor genes and make malign structures to shrink. The video mentioned a product that works with the BRАF protein that induces cells to uncontrolled division; the drug led to the remission in the patient with metastasizing melanoma. Such treatment was effective in the case of cystic fibrosis. In the case of the breast cancer the technology helps to evaluate the aggressiveness of the condition and make a personalized decision about chemotherapy. The video also mentioned the pre-implantation genetic diagnosis – an early-staged technology that prevents the development of inherited disorders in
The more we know about genetics and the building blocks of life the closer we get to being capable of cloning a human. The study of chromosomes and DNA strains has been going on for years. In 1990, the Unites States Government founded the Human Genome Project (HGP). This program was to research and study the estimated 80,000 human genes and determine the sequences of 3 billion DNA molecules. Knowing and being able to examine each sequence could change how humans respond to diseases, viruses, and toxins common to everyday life. With the technology of today the HGP expects to have a blueprint of all human DNA sequences by the spring of 2000. This accomplishment, even though not cloning, presents other new issues for individuals and society. For this reason the Ethical, Legal, and Social Implications (ELSI) was brought in to identify and address these issues. They operate to secure the individuals rights to those who contribute DNA samples for studies. The ELSI, being the biggest bioethics program, has to decide on important factors when an individual’s personal DNA is calculated. Such factors would include; who would have access to the information, who controls and protects the information and when to use it? Along with these concerns, the ESLI tries to prepare for the estimated impacts that genetic advances could be responsible for in the near future. The availability of such information is becoming to broad and one needs to be concerned where society is going with it.
It was in the 1980’s that scientist began looking at alternative ways of treatments, one is gene therapy. Scientist would insert human genes into a bacteria cell. Then the bacteria cell would transcribe and translate the information into a protein. Once that is done the scientist would then introduce the protein into human cells. Gene therapy can be simply viewed as inserting bits of foreign DNA into a patient’s tissue in hope...
In Gattaca, the plot focuses on the ethics, the risks, and the emotional impact of genetic testing in the nearby future. The film was released in the 90s; yet in the present, the film does not give the impression of science fiction. Today, genetic testing is prevalent in many aspects of the scientific community. This paper will describe genetic testing, its purpose, diagnostic techniques that use genetic testing, relating Huntington’s disease to genetic testing, and the pros and cons of genetic testing.
Over 40 years ago, two men by the names of James Watson and Francis Crick discovered deoxyribonucleic acid, or DNA. DNA is hereditary material in humans and almost all other organisms (What is DNA?). From this finding, gene therapy evolved. Today, researchers are able to isolate certain specific genes, repair them, and use them to help cure diseases such as cystic fibrosis and hemophilia. However, as great as this sounds, there are numerous ethical and scientific issues that will arise because of religion and safety.
Throughout the years many people have asked the same question, ‘What is Genomics and is it really ethical?’ Genomics has been seen as unethical and it is largely frowned upon in many societies today but scientists believe otherwise. Genomics has recently become a major breakthrough for scientists and they are working on many ways to show the world that it is in no way unethical and could benefit us and generations to come. Genomics is the study of a genome which is the complete set of DNA in organisms. In this field, specialists go through thorough efforts to determine the entire DNA sequence of an organism and map out its genetics. With this information scientist are able to study the genes that are involved in diseases like cancer, diabetes and heart diseases and possibly find a way to alter them so that those types of serious diseases may be avoidable for future generations. Fred Sanger was the first man to originate Genomics when he sequenced the genomes of a virus and of a mitochondrion, him and his group established different genomic techniques of sequencing between 1970 and 1980. From 1970 till know Genomics has grown into The Genomic Science Programme which falls under The Human Genome Project and both are led by the National Human Genome Research Institute in America and in April 2003 this project was successfully completed with a high-quality version of the full human genome available for public view.
“Today some patients have their genomes sequenced to shed light on genetic diseases or illnesses like cancer, but one day people will not wait until they are sick, for they will already know the data at birth, says Arthur Beaudet. In this day in time scientist are testing out procedures in which parents will be able to alter their child’s genes. This means parents will have the will to create their child in a way they see fit. Although, this is a technological breakthrough for scientist, many obstacles stand in the way of widespread use of prenatal DNA sequencing. To understand prenatal DNA sequencing scientist must look into the genetic inheritance and DNA of the child, for the procedure itself it creates many positive and negative effects; for the uncertain parents they must look into the procedure and learn from genetic counselors which could be the best choice, not only does providing a genetic counselor endure genetic counselors prenatal DNA sequencing also requires tons of money alone.
Epigenetics is the word that is used for genes that are modified in order to assist certain genome sequences that lead to diseases and disorders. Epigenetics has come a long way since the first genome sequence had its draft breakthrough in the year 2000 (NOVA 2012). From depression to cancer, epigenetics has made its way through to provide families with the appropriate knowledge and perhaps medication in order to avoid these diseases and disorders in the future.
In September 14, 1990, an operation, which is called gene therapy, was performed successfully at the National Institutes of Health in the United States. The operation was only a temporary success because many problems have emerged since then. Gene therapy is a remedy that introduces genes to target cells and replaces defective genes in order to cure the diseases which cannot be cured by traditional medicines. Although gene therapy gives someone who is born with a genetic disease or who suffers cancer a permanent chance of being cured, it is high-risk and sometimes unethical because the failure rate is extremely high and issues like how “good” and “bad” uses of gene therapy can be distinguished still haven’t been answered satisfactorily.
Due to the human genome project and other genetic research, tests for mutation which cause diseases have been developed. The list of these illnesses include several types of cancer. Doctors have estimated that as many as 3,000 diseases are due to mutations in the genome. These diseases include several types of colon cancer in which three different genetic tests have been already developed. Debates have arisen on whether these tests should be used regularly or not. Questions including the patients= rights of privacy and the possibility of loss of health or life insurance have been argued over in both the media and political arena.
The genetic technology revolution has proved to be both a blessing and a blight. The Human Genome Project is aimed at mapping and sequencing the entire human genome. DNA chips are loaded with information about human genes. The chip reveals specific information about the individuals’ health and genetic makeup (Richmond & Germov 2009).The technology has been described as a milestone by many in that it facilitates research, screening, and treatment of genetic conditions. However, there have been fears that the technology permits a reduction in privacy when the information is disclosed. Many argue that genetic information can also be used unfairly to discriminate against or stigmatize individuals (Willis 2009).
The Human Genome Project is the largest scientific endeavor undertaken since the Manhattan Project, and, as with the Manhattan Project, the completion of the Human Genome Project has brought to surface many moral and ethical issues concerning the use of the knowledge gained from the project. Although genetic tests for certain diseases have been available for 15 years (Ridley, 1999), the completion of the Human Genome Project will certainly lead to an exponential increase in the number of genetic tests available. Therefore, before genetic testing becomes a routine part of a visit to a doctor's office, the two main questions at the heart of the controversy surrounding genetic testing must be addressed: When should genetic testing be used? And who should have access to the results of genetic tests? As I intend to show, genetic tests should only be used for treatable diseases, and individuals should have the freedom to decide who has access to their test results.
The age of genetic technology has arrived. Thanks to genetic technological advancements, medical practitioners, with the help of genetic profiling, will be able to better diagnose patients and design individual tailored treatments; doctors will be able to discern which medications and treatments will be most beneficial and produce the fewest adverse side effects. Rationally designed vaccines have been created to provide optimal protection against infections. Food scientists have hopes of genetically altering crops to increase food production, and therefore mitigate global hunger. Law enforcement officers find that their job is made easier through the advancement of forensics; forensics is yet another contribution of genetic technology. Doctors have the ability to identify “high-risk” babies before they are born, which enables them to be better prepared in the delivery room. Additionally, oncologists are able to improve survival rates of cancer patients by administering genetically engineered changes in malignant tumors; these changes result in an increased immune response by the individual. With more than fifty years of research, and billions of dollars, scientists have uncovered methods to improve and prolong human life and the possibilities offered by gene therapy and genetic technology are increasing daily.
In the article, DNA Fingerprinting: Cracking Our Genetic “Barcode” by Elaine N. Marieb, she describes the process and uses of DNA fingerprinting. The importance of DNA is very helpful because it makes it easier to identify different individuals through their genetic material. In another interesting article, Interface Facts by Katie L. Burke, she mainly focuses on internet video games that could be an effective method for scientific research for scientists and non-scientists. DNA and Technology have emerged and are a great benefit to humans to help find matches such as long-relatives, a murderer in a case, and personal background information whether alive or deceased. Also DNA and Technology can be useful for public awareness reasons too.
The American Cancer Society publishes current advances made in cancer research on their website. Many of the exciting discoveries about how best to treat the disease focus on the genetic aspects associated with certain types of cancer. In addition, treatments aimed at genetic solutions to cancer may be more effective and may cause fewer adverse side effects than traditional cancer treatments (American Can...
Genetic testing, also known as screening, is a rapidly advancing new scientific field that can potentially revolutionize not only the world of medicine, but many aspects of our lives. Genetic screening is the sequencing of human DNA in order to discover genetic differences, anomalies, or mutations that may prove pathological. As genetic screening becomes more advanced and easily accessible, it presents society with difficult questions that must be asked about the boundaries of science and to what degree we are allowed to tamper with the human genome. To better understand the potential impact of genetic screening on our society, we must examine the potential benefits in comparison to the possible negative impact it may cause. With this knowledge in hand, we can examine what the future holds for this field of study and the best possible direction to take.
