Cracking Your Genetic Code: A Review of Genetic Testing
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.
Genetic testing
Description of genetic testing
By using identified gene mutations that are known to cause diseases, asymptomatic individuals are able to discover if they are at risk for specific genetic conditions; this is known as genetic testing. Unfortunately, genetic testing can vary in its predictive ability. For example, Huntington disease, Duchenne Muscular Dystrophy, Fragile X syndrome and multiple endocrine neoplasia type 2 are conditions that can be determined by genetic testing (Samen, 1996). In contrast, for multifaceted diseases like Alzheimer’s, breast and ovarian cancer and colorectal cancer, predisposition can be determined with genetic testing. However, an absolute diagnosis of those diseases cannot be made (Heshka et al., 2008).
Examples of genetic testing in “Cracking Your Genetic Code”
In the film, two contrasting examples of genetic testing are shown. The first example is of the twins Noah and Alexis Beery, who are stricken with a rare disease that mimics cerebral palsy. Through genetic testing, doctors discovered that the twins could be treated with dopamine. By sequencing their entire genome, the twin’s lives were saved. The second example is Andrew S...

Forbidden Knowledge: Ethical Considerations in Genetic Research Essays

- Researchers or Nurses who are involved in research studies can encounter numerous ethical issues when the research comprises human beings and animals in any discipline. Code of ethics was endorsed by the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research. “The commission, established by the National Research Act (Public Law 93-348), issued a report in 1978 that is referred to as the Belmont Report, which provided a model of guidelines adopted by the disciplinary organizations of the United States” (Polit & Beck, 2008, p....   [tags: Genetics, Ethics]

The Pros and Cons of Genetic Testing Essay

- In 2003, the Human Genome Project was completed. The project was an international research effort whose ultimate goal was to sequence the human genome and identify its genes. Upon completion, the Human Genome Project provided a complete sequence of the nearly 3 billion base pairs in the human genome. By essentially creating a blueprint of what makes a healthy human, we know what a normal, un-mutated genome looks like. That being said, genetic testing is now available to essentially anyone. While genetic testing may put us a great advantage scientifically, it could also be a set-back....   [tags: Genetic Testing Essays]

Genetic Testing Essays

- Deoxyribonucleic acid (DNA) is the building block of life. The backbone of DNA is composed of four different bases: thymine (T), guanine (G), adenine (A), and cytosine (C). Each base is then attached to a phosphate group and a sugar, forming a single nucleotide. Genetic information is encoded by the sequence of nucleotides in the strand; therefore, the quantity and sequence of nucleotides in a strand of DNA differs depending upon the organism. Each base’s chemistry renders it specifically complementary with one other base (A-T and C-G)....   [tags: DNA, Mutations, Genetic Testing]

Essay on Genetic Testing of African Americans

- Introduction Many people have often wondered about their past and where they come from, but different people react differently when it comes to finding out where they originally came from. Some actively seek to find out for themselves through researching their family history or by undergoing genetic testing, and their reaction may be either positive, or even negative, especially if their racial origin is not what they might have expected. The Afro-American community is particularly receptive towards such testing because it helps them to identify with their African origins and deal with the emotional impact of their upsetting history in which their ancestors were forcibly brought to the Ameri...   [tags: Genetic Testing Essays]

Genetic Code Expansion By Degeneracy Reprogramming Essay

- Genetic Code Expansion by Degeneracy Reprogramming of Arginyl Codons Abstract The genetic code in most organisms codes for one of 20 proteinogenic amino acids or translation stop. To code for more than 20 amino acids using a single coding system, one of stop codons has been traditionally reprogrammed to encode a non-proteinogenic amino acid. Though this approach was proven to work, usually only one extra amino acid is added to the amino acid repertoire. In this study, we used another approach to incorporating non-proteinogenic amino acids into proteins using a sense codon....   [tags: Amino acid, Protein, Genetic code, Pyrrolysine]

The Disadvantages of Genetic Testing on Children Discussed in Dena Davis' Book Genetic Dilemmas

- In chapter four of her book Genetic Dilemmas, Dena Davis asserts that it is unethical for parents to subject their children to genetic testing for the markers of adult-onset genetic diseases because it places an unfair constraint on a child’s right to an open future. It both removes the child’s ability to choose whether to be tested as an adult and has the potential to negatively alter the overall trajectory of their lives. While the current consensus amongst medical professionals is that such testing should be prohibited (Davis, _____), many concerned parents correctly point out that discouraging such testing creates a conflict of interests between the “beneficence model of patient care and...   [tags: genetic dilemmas, medical, genetic testing]
