The Effects Of Genetic And Genomics On Health And Disease

Eliana Giller Introduction: Genetic and genomics both play roles in health and disease. Body 1: Genetic make up comes from mutations within DNA. Deoxyribonucleic acid. Each cell contains 9 feet of DNA. In an average mean you eat approximately 55,000,000 cells; this is equal to about 93,205 miles of DNA. DNA is formed by a specific type of molecule called nucleotides. Each nucleotide has a phosphate group, sugar group, and nitrogen base. The 4 types of nitrogen bases are adenine, thymine, guanine, and cytosine. The order of these bases is what determines DNA’s genetic code. For example, the order of letter in the alphabet can be used to put together a word, the order of nitrogen bases in a DNA sequence can form†¦show more content†¦For example, allele for brown eyes is dominant, so you only need one copy of â€Å"brown eyes† to be provided with them. If both alleles are dominant, its called codominance. The resulting characteristic is due to both alleles being expressed equally. Example, blood group AB result of codominiance of the A and B domi nant rules. Recessive alleles on the other hand only show their effect if the individual has two copies of the allele. This is because recessive is much less powerful than dominant. The allele for blue eyes has to be provided with two copies of the â€Å"blue eye† allele. In conclusion, dominant and recessive traits show and express who a person really is. Body 4: Genetic mutations are permanent changes to a cells DNA. DNA and RNA (ribonucleic acid) are chemical blueprints for your entire body. Every living organism has genetic materials that controls all of its body s functions. It also determines many physical traits. Eye color is completely formed by genes but in fact, height is established by genes plus environment. Such as past generations heights. Genetic code can change over time, but most of the time it doesn t effect you because it s protected by DNA repair so they don t become permanent mutations. When the changes are strong, the DNA repair is to week to handle it so the changes unfortunately become permanent, which signals that it s going to effect you and it s deleterious.Show MoreRelatedImpact Of Genomics On Health And Disease1366 Words   |  6 PagesImpact of Genomics in Health and Disease The field of genomics has an incredible relevance starting from biomedical research to health care and then personalized health care to patient and their families. Over the last two decades, there has been great advances in the field of genomics, a discipline in medicine that involves a person’s genetic information and its use in the clinical practice for treatment and prevention of a disease. With the advancement in technological capabilities and addressingRead MoreGenomics - Disruptive Technologies : Creating A New Healthcare Paradigm905 Words   |  4 PagesGenomics - Disruptive Technologies: Creating A New Healthcare Paradigm Disruptive technologies have played a significant role through the ages in leapfrogging the paradigms of healthcare systems Innovation and medicine go together. In modern times medicine has been transformed by waves of discovery that have brought marvels like antibiotics, vaccines and heart stents. Disruptive technologies have played a significant role through the ages in leapfrogging the paradigms of healthcare systems.

There are several arguments contrary to genomic research and some are supporting it. For instance The Director of Cancer genetics center at Johns Hopkins university says â€Å"it may become one important determination in patient care, but certainly not the only one† [source]. Several studies doubts that genomic research providing any extra information about the possibility of getting common diseases, including heartRead MoreHistory Of Dr. Clay Siegall Espouses Landmark Cancer Treatment Therapies1059 Words   |  5 Pagesrevolutionary Seattle Genetics research facility--are now turning to antibody-assisted cancer treatments and precisely targeted cures instead of treating cancer with a cocktail of chemic als and radiation that generate risky side effects and damage the healthy tissue that patients need to recover. Cancers are among the most frightening and difficult-to-treat illnesses. Ranked as the leading cause of death and disability, cancer is actually an umbrella term that covers many different diseases.

As stated, the HGP sought to identify all the genes in human DNA, determine the sequences of the three billion chemical base pairs that make up human DNA, store this information in databases, improve tools for data analysis, transfer related technologies to the private sector, and address the ethical, legal, and social issues that may arise from the project. In favor of achieving these goals, scientists studied the genetic makeupRead MoreWhy The Cancer Experts Support Gene Testing To Diagnose Cancer1055 Words   |  5 Pageswatershed breakthrough in medical technology that promises to generate paradigm changes in medical treatments. More than a decade ago, scientists at the Human Genome Project finally mapped the genetic blueprint of Homo sapiens. This accomplishment enables medical staff to â€Å"read† genes and practice genomic medicine - such as identifying particular strains of pathogens like tuberculosis.

They return results to participants on genetic health risk, carrier status and wellness (how genes play a role in lifestyle choices). Genetic health risk informs individuals on how their genetic profile influences risk for certain diseases, for example having the e4 variant in the APOE gene for Alzheimer’s disease. Limitations to this method are: firstly, all possible variants for Alzheimer’s are not included, secondly onlyRead MoreEssay On Genome Sequencing1094 Words   |  5 Pagespresence of disease markers. The current newborn screening programs are fast, cost effective, and accurate in identifying disease before symptoms appear. Genome sequencing cost have now decrease to a price range like other complex medical test to be readily available for clinical application. It is possible for geno me sequencing to replace or supplement the existing traditional panels for newborn screening tests. The newborn genome sequencing can provide more information on the health of the individualsRead MoreThe Power Of Modifying Genetics1351 Words   |  6 PagesThe power of modifying genetics is at our fingertips, allowing us to change the genes of living creatures, which of course includes humans. The concern is; what genes should be modified, and which genes should be left alone. A company called 23andMe, named after the 23 pairs of chromosomes in a human cell, will provide ancestry genetic reports and uninterpreted raw genetic data using only a kit. Created in 2006, out of Mountain View, California, the company specializes in three different productsRead MoreEssay On Informed Consent798 Words   |  4 PagesEthical issue: Informed Consent What did you learn? I learned that informed consent is essential when conducting a genomic research and publish individuals and their families’ private genetic information. The individuals and their families have right to know how their genome can be used for science. In Henrietta Lacks case, the European researchers took down their public data, and the publication of the University of Washington paper was stopped due to they did not get family’s permission (Skloot
