And in some situations women choose to terminate pregnancies because of the results. One test done on newborns has been in practice since the sixties. Phenylketonuria is a disease that can cause retardation if not caught early enough in a child's development. The government has mandated the testing of newborn for this metabolic i mbalance that can be treated by proper diet. (Blatt 1997) Many other diseases can be diagnosed at birth with relatively no danger to the infant as compared to the invasive procedure describe earlier.
Gene Technology Research | Jessica Le Genetic Modification Purpose Genetic modification (GM) is a complex biotechnology procedure used to modify certain genes of many organisms. Scientists have been modifying genes, especially in plants, to collect the traits which are most desirable. These traits include better nutritional contents or an enhanced resistance to disease and herbicides. Scientists are aiming to use genetic engineering for reasons such as, creating cures for genetic diseases and grow plants that are engineered to be resistant to insecticides. Genetic modification will benefit people with genetic disorders by altering their genes to treat or fight the disease.
Older pregnant women who usually have more complications during pregnancy benefit from genetic screening. Doctors usually recommend “more invasive procedures” in which actual fetal cells are collected from the womb’s amniotic fluid or placenta . (Golden) Receiving the results from the tests, she can determine whether it is safe for her to continue with the pregnancy, especially since some tests provide accuracy as high as ninety-nine percent. (Golden) Unfortunately, not all test results come out positive. Approximately ninety-five percent of couples who receive “bad” news from genetic scr... ... middle of paper ... ...nsequences, especially because of genetic screening.
The Advantages and Disadvantages of Developing Genetically Engineered Organisms Genetic engineering is the method of changing organisms' characteristics inherited by alerting it genetic material. This often done to cause micro organisms, such as bacteria and viruses, to synthesize increased yields of compounds, to form entirely new compounds, or to adapt to different environments. Other uses of this such of a technology, is known as the recombinant DNA technology, it includes gene therapy, which is the supply of a functional gene to a person with a genetic disorder or with other diseases such as acquired immune deficiency syndrome (AIDS) or cancer. Genetic engineering involves the manipulation of deoxyribonucleic acid, or DNA. Important tools in this process are so-called restriction enzymes that are produced by various species of bacteria.
In fact, British scientists have created a test that analyzes embryos for genetic diseases and can be used to determine what genes can cause certain diseases (Steere). Also in 1997 designer babies were made by Jacques Cohen to aid women who were infertile and could not have children. Shannon Brownlee told about how people can genetically alter their children when she said, “Today, any couple with several thousand dollars to spare can choose the sex of their offspring, while parents who are carriers for certain genetic disorders can undergo IVF and have the resulting embryos genetically tested to ensure their children are free of disease.” This means that parents are currently able to choose the sex of their children and if they are carriers of diseases, they can use In Vitro Fertilization to make sure that the future children ar... ... middle of paper ... ...destroying the chance of cells such as cancer cells from being made.

“[...] any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use.” This statement is often used to describe the fundamental aim of biotechnology around the world. Karl Ereky, one of the foremost proponents of the term biotechnology foresaw that “merging biology and technology could be used to transform living substances into products that are more useful than in their natural state,” thus benefiting society by meeting human needs or demands to improve our quality life. Although the use of living systems to make a product has an established history, the modern definition of biotechnology is usually associated with recombinant DNA technology. The idea of recombinant DNA was first proposed by Peter Lobban but the founding principles were published in 1973 by Stanly Cohen and Hebert Boyer. “Recombinant DNA technology allows DNA to be produced via artificial means.
Any medical dictionary will loosely defines it as “the group of applied techniques of genetics and biotechnology used to cut up and join together genetic material and especially DNA from one or more species of organism and to introduce the result into an organism in order to change one or more of its characteristics” (“genetic engineering”). While most genetic research is for the purpose of medical advancement and the treatment of incurable genetic defects like Down’s syndrome, eugenics was once pursued under the guise of genetic engineering for the greater good.

After I watched this video, I believe that every woman have the right to do research and decide on her own birthing plan rather than following orders by her doctors. Before I think that giving birth in the hospital is the best way to give birth, but at this video show me I got change my mind a lot. Technology has become extremely popular during the birth process used by the doctors. The hospitals are capable of doing more damage to the infant and mother during the birth process than natural birth. In the hospital, the doctor uses the medicines and procedures to allow the woman birth to be easier, but sometimes that process has effects on the baby.
Isolation of the vector DNA from the host cell’s DNA and then is purified. Biotechnology products are those that are manufactured by a recombinant DNA Technology which is produced by biotechnology. These products include vaccines, antibiotics, transgenic plants, genetically modified organisms and lastly beverages. Biotechnology is not just one technology but several of them as it can produce an extensive variety of products across a range of industrial sectors like drought-resistant crops, ethanol from fermentation, microorganisms which clean up oil spills and many others. According to Yourgenome.org, Gene therapy is basically when the DNA is introduced into a patient to treat a genetic disease.
The segments of DNA, which have been associated with specific features or functions of an organism, are called genes. Molecular biologists have discovered many enzymes, which change the structure of DNA in living organisms. Some of these enzymes can cut and join strands of DNA. Using such enzymes, scientists learned to cut specific genes from DNA and to build customized DNA using these genes. They also learned about vectors, strands of DNA like viruses, which can infect a cell and insert themselves into its DNA.
