Genetics

What is genetic engineering? Also known as genetic modification, genetic engineering is the process of changing the DNA in an organism's genome. This would involved changing or altering one base pair, or inserting or deleting a whole region of DNA in a sequence. For example, this could be a mutation, such as a point mutation or frameshift mutation. A point mutation is when one nucleotide is substituted for another and can have either an effect or not. A frameshift mutation involves the…

The article Genetic Testing in Newborns gets a Critical Breakthrough, written by Alice Park, addresses future breakthroughs in the medical future. Genetic testing in newborns is definitely a development in the treatment of babies, especially those born prematurely and with health/development issues. By being able to test DNA and get results in as early as 26 hours and as late as 50 hours it dramatically increases the outlook on the treatment rates and the survival rates in high sensitivity…

past, genetic research has advanced a great deal. For many centuries, it was believed that God had created the human species; however, due to the researches and experiments done by scientists like Hippocrates, Aristotle, Charles Darwin, Gregor Mendel… it is now accepted that the true force behind evolution, is the adaptation of the genetic code to the environment. As the research in eugenics advances, researchers discover an array of different possible applications such as: germ-line genetic…

In sequence 2, the DNA coded for the gene Apolipoprotein E, also known as APOE. The APOE protein is made from instructions from the APOE gene. This protein binds with fats from the body to form lipoproteins, which are responsible for packaging cholesterol and other fats and carrying them through the bloodstream. There are three different versions of the APOE gene. They are known as APOE e2, e3, or e4. Different forms of APOE have been shown to cause a variety of different diseases. The most…

GENETIC TRANSFER MANIPULATION Humans have been manipulating the natural genetic transfer of animals and plants for a long time. Cloning and selective breeding are well known examples of genetic transfer manipulation. This report will focus on these two manipulations, and the implications they can have on the individuals, and the populations too. In order to show why genetic transfer manipulations are used, and to see the implications of it, the cases of “Dolly” the cloned sheep, and domesticated…

The notion that there are genetic causes of speech, hearing, and voice disorders is relatively new, and studies in this field are beguiling to emerge as time passes. The article Exploring genetic and environmental effects in dysphonia: a twin study attempts to "explore the existence of genetic effects as well as the interaction between potential genetic effects and a voice-demanding occupation on dysphonia.” As a scientific study, the article first provides evidence that the research can be…

First and foremost, Genetic testing, when it’s applicable is an effective apparatus to assess a patient’s risk of disease. With just a tester of blood or saliva, this can unravel the patient body’s genetic defect and foresees upcoming complications vary between cancer to Alzheimer’s disease. Genetic testing as technology become very prominent, back then it was extremely demanding and steep for just about anyone, even those in advanced labs to executed. However, today it is rapidly becoming an…

even intelligence could all be chosen. Designer babies, or build-a-baby, are typically thought of in context of science fiction, but the possible technology used create them already exist. Preimplantation genetic diagnosis (PGD), created in 1989, was one of the first iterations of a genetic profiling technology that could literally allow people to ‘design’ their offspring. It works in tandem with in-vitro fertilization (IVF), since fertilization in a laboratory after egg retrieval is needed in…

Genetics is the field of study that investigates how particular qualities or traits are passed on from parents to their offspring. Genetic information is passed from parent to offspring via chromosomes. Human beings have 23 pairs of chromosomes which contain between 20,000 to 25,000 genes, some of which determine their inherited physical traits such as eye colour, skin colour, and body shape. Offspring can also inherit some non-physical traits from their parents including disease. Sickle Cell…

as it is followed by the potential risks for each scenario. Although there is potential for DNA research to innovate the healthcare of the humankind, it is yet too dangerous to apply in our daily lives without being aware of the exact outcomes. Genetic engineering allows scientists to modify the genes in the crops grown to produce bigger and faster growing plants that resist diseases. They can be customized to thrive in harsh environments. This breakthrough hints at the possibility for a…
