Gene Testing : Genes Affect A Single Gene Essay

The view over genetic testing starts with establishing necessary definitions and discussing its purpose in our world. To start off, the human body is a complex multicellular system. Every cell in the body is comprised of the same DNA (with some exceptions), which stores our genes. These genes are the set of instructions that encode the proteins necessary to create and maintain the human body. The issue is that some genes can undergo a variety of mutations during development that cause an array of complications or disease. Gene therapy can modify the designated abnormal genes to reach normalcy, while genetic engineering focuses on enhancement and surpassing what is normal. However, the goal of genetic testing is to identify the abnormalities

One of the benefits of prenatal screening is to enable early detection of the developmental defect embryology. This embryology developmental defect may be due to the mutation or genetic inheritance. Mutation is a condition characterized by permanent change in the DNA sequence that makes up a gene. It can range in different sizes from a single DNA building block (DNA base) to a large segment of a chromosome. On the other hand, genetic inheritance is a condition whereby parents pass traits such as height and other characteristics to the children by chromosomes. “Sonograms, genetic tests and a new test called pre-implantation genetic diagnosis -- which is a genetic test conducted on embryos for people attempting pregnancy through in vitro fertilization -- allow women to better predict if the infant will have a genetic defect” (New York Times Magazine, 2006). Thus thorough these tests, medical practitioners are able to identify and make early preparation toward any abnormalities of the fetus.

The medical advances being made feasible by genetic testing are very exciting. It is possible for people with predispositions for genetic defects to know in advance if they will have a healthy child or not. If they find out there is a problem they can choose to terminate the pregnancy or they can prepare in advance for their child's special needs. There is even new technology called Ex Utero genetic testing. This test is performed on eggs fertilized through in vitro fertilization before they are even put in the mother's uterus. Understanding genes in the developing human will help doctors understand the nature of genetic diseases and may lead to countless other medical breakthroughs. Though it is probably a long way off doctors may one day be able to manipulate genes. If this is possible some genetic problems may be cured.

Genetic testing is used to determine the risk of a patient or patient’s offspring developing genetic diseases. This is done with DNA sequencing in adults and preimplantation genetic diagnosis (PDG) on embryos. These methods of genetic testing are effective means of determining the likelihood of developing diseases such as Huntington’s disease, a disease resulting from trinucleotide repeat on chromosome 4p16.3 that causes uncontrollable muscle movement and decrease in cognitive function. However, they only determine probability, which isn’t an entirely reliable means of knowing whether or not symptoms will arise.

Genetic profiling is a contemporary issue relating to the individual and technology which restricts access to unbiased decisions and privacy. Genetic profiling interferes with the individuals bodily, genetic and behavioural privacy, as it can be used for the benefit of identifying bodies to using the results of a DNA test to choose whether to employ one individual over another, due to future concerns. It can easily be argued that genetic profiling is in the need of law reform as a result of legal implications and the lack of individual’s rights.

As you can see genetic testing is very important and can affect a child's and parents lives for the better and the worst. Children all over the world have serious genetic diseases that affect their life on a daily. Some of these diseases are Achondroplasia, Down syndrome, and Turner's syndrome. Many believe genetic testing is a good way to test for these genetic conditions before the child is even born, but others think that it can harm the baby very badly and even cause a miscarriage, so they choose not to do this kind of testing. Knowing about the most serious genetic diseases is very important for expecting parents to be informed as well as being

The gene's information is then transmitted down through the generations of relatives. With genetic testing and genetic engineering certain genes can be avoided, for example Huntington's disease, or certain physical traits can be chose, such as eye color. This can be considered a form of eugenics; the choosing of physical traits in future children is starting to gain more media attention and is a very controversial topic that is often referred to as designer babies.

Genetic testing is when tests are done on the blood and other tissue to find genetic disorders in an individual. It is used as a healthcare tool to detect gene variants associated to a certain disease or disorder, and is used non-clinically for paternity testing and forensics. There are many different methods of testing, usually done with a blood sample. Other methods include diagnostic testing, carrier testing, prenatal testing, pre-implantation genetic testing, newborn screening, pharmacogentic testing, and a few others.

Genetic testing, can affect a person’s life in many ways. Genetic testing is a type of medical testing that identifies changes that occur in chromosomes, proteins, and genes. These changes that occur can be associated, and often are associated with inherited

Genetic testing is a medical test of one’s DNA that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition which can help determine an individual's chance of developing or passing on a genetic disorder. In addition, knowing one’s genetic code can help individuals improve their wellness, prevent the onset of diseases they are at risk for, or lessen the harmfulness of diseases they do contract. NOVA’s documentary on PBS, “Cracking Your Genetic Code” demonstrates what exactly genetic testing is, how genetic testing is performed, and in addition the film showed stories about some individuals that have benefited from these special DNA techniques. The film plot focuses

Genetic testing is normally used to determine if a person is carrying a specific mutated or altered gene which can cause a specific medical condition. JL’s parents would benefit from this because genetic testing would determine how likely it is that JL’s parents are to pass on the same mutated gene to another child. This would also determine if the mutated gene was inherited from the parents of weather or not it was a result of a random mutation.

Although the gene chip will enable an individual to know whether he/she has a genetic disease, that person may not want to know the information. Many people are frightened that a positive finding on a genetic test will result in discrimination and ostracism because the society will consider them abnormal (Easthope 2005). The other concern is that with genetic test information one might lose or might be unable to get a job or insurance. There have been concerns that with the knowledge of one’s medical information after a gene test, he/she might suffer a psychological problem especially when the results reveal that one suffers from a terminal disease or has high possibility of suffering from one (Willis 2009).

A highly conserved gene will be used to identify a prokaryotic species isolated from the body. Fundamental lab techniques will be also explored and utilized, such as amplifying using PCR, cloning, and transforming the gene into a host cell. DNA electrophoresis and specific substrate plating will serve as analysis check points. The final product will be sequenced and compared to similar species to observe phylogenetic relationships.

genetic testing, everything has changed. She notes that clinicians now have the ability to diagnose, treat, and monitor a patient’s illnesses or disease progression in an entirely different manner. This is a far cry from the old medical model of responding to a disease (or defect) only after it appears, and then prescribing the recommended medication or intervention. These genetic medical advances sound miraculous and promising, but the ability to test, screen and provide early intervention does not come without many major ethical dilemmas.

The study of genetics includes not only the study of normal DNA, but also of the mutations within a DNA. A mutation is a slightly distorted gene. These mutations can have an effect on a person, both physically and mentally. Although genetics may seem to be just about the genes, scientists are beginning to see a connection between gender and genetic mutations.
