The Discovery of DNA’s Molecular Structure - Theoretical models for the molecular structure of DNA can be likened to scientific theories. DNA’s structure was determined largely because scientists scrutinized the relationship between theory (a particular theoretical model of DNA) and observation (x-ray crystallographic patterns, or bonding patterns between bases and sugar-phosphate groups, for example). Inductivists, falsificationists, Kuhn, and Feyerabend all have different accounts of how scientists have related theory to observation....   [tags: Science Genetics Papers] 2646 words

Cystic Fibrosis and Gene Therapy - Cystic Fibrosis and Gene Therapy The average life span of a person with Cystic Fibrosis is 25-30 years of age. Although the more traditional treatments of this disease are adequate, is there something else that could be even better. Gene therapy is fast becoming one of the more studied aspects of genetics today. Let's take a look at some details of Cystic Fibrosis and gene therapy. Technical Aspects Cystic Fibrosis (CF) is the most common fatal genetic disease in the United States today. CF is an autosomal recessive disease that occurs approximately one out of 3,300 live births (Cystic Fibrosis Foundation, 1998)....   [tags: Science Genetics Biology Papers]

The Human Genome Project - The Human Genome Project The human genome project is something that I have been very interested with ever since first learning of it. I had heard bits and pieces of what it is about, but my interest was greatly stimulated by Dr. Whited in basic genetics 311 last spring. The discussion that we had regarding the project left me with several ideas and questions about not only the process and ethics involved, but the future of the study of genetics as a whole. To begin discussion about the HGP, we first must understand what it is....   [tags: Genetics DNA Science Essays]

Examining the Crosses Between Drosophila Fruit Flies - Examining the Crosses Between Drosophila Fruit Flies Introduction The major topic of this experiment was to examine two different crosses between Drosophila fruit flies and to determine how many flies of each phenotype were produced. Phenotype refers to an individual’s appearance, where as genotype refers to an individual’s genes. The basic law of genetics that was examined in this lab was formulated by a man often times called the “father of genetics,” Gregor Mendel. He determined that individuals have two alternate forms of a gene, referred to as two alleles....   [tags: Fruit Flies Experiments Genetics Biology Essays] 613 words

The Dark Side of Genetic Engineering - I never knew what genetic engineering was until I watched a special on the Discovery channel. The special showed scientists forming the first “perfect” embryo. What was very shocking was that the scientists kept asking each other what traits this embryo should compose of. To me that was disturbing and unethical to make a living human being based on what traits the parents would want them to have. This process goes against nature just as Francis Bacon said “if we would control nature, we must first obey her” (Fox 193)....   [tags: Genetic Engineering Essays] 1104 words

Genetic Engineering Is Not Safe - Genetic engineering is the intended modification to an organism’s genetic makeup. There have been no continuing studies on this topic or action so there is no telling whether or not it is harmless. Genetic engineering is not safe because scientists have no absolute knowledge about living systems. Given that, they are unable to do DNA surgery without creating mutations. Any interference on an organism’s genetic makeup can cause permanent damage, hereditary defects, lack of nutritious food, or a spread of dangerous diseases....   [tags: Genetic Engineering Essays]

Pros and Cons of Gene Therapy - Pros and Cons of Gene Therapy Gene therapy is thought of by some people as an terrific discovery that could greatly improve the human population and also give people with certain disabilities some glimmer of hope. And on the other side of the coin there is some people that think we have no business playing God. They feel that playing God may possibly cause devastating effects to the human gene pool and may also led to misuse.

Newborn Genetic Screening - The purpose of newborn genetic screening is to screen newborns for potential health concerns. Newborn genetic screening started in 1965 with the testing of one disorder, phenylketonuria (WDHS). Since then, newborn genetic screening has evolved and over 4 million newborns are screened in the U.S. every year (CCHC Report). Currently, in the state of Wisconsin, there are 47 different disorders that are tested for (WDHS). The process of screening newborns is a relatively short procedure. Before a newborn leaves the hospital a nurse pricks its heel and takes a few drops of blood and deposits it on a special test paper....   [tags: Genetic Disorders]

Ethical Controversies Involved in the Use of Germ-line and Somatic Gene Therapies - Ethical Controversies Involved in the Use of Germ-line and Somatic Gene Therapies Abstract There are many sides to the issue of using germ-line and somatic germ therapies. Many people argue that it should be stopped completely, whereas others argue that both germ therapies should continue for the benefit of all people. There are other arguments that lie somewhere in between. Most of the controversy is caused by germ-line gene therapy because it can be passed on through generations. Somatic gene therapy has more support and funding but is still considered untrustworthy by many who believe it may also affect the germ-line in some cases....   [tags: Biology Medical Biomedical Genetics]

Gene Therapy : Ethics, Progress, and Future - The Factor of Gene Therapy: the Ethics, Progress, and Future Abstract Erasing genetic diseases from the human race has been a vital role in science. However, there is a point where the moral standards have interrupted the advancement of curing genetic diseases. One of the many sciences that have the ability to completely wipe out the future of any genetic diseases, gene therapy, is being stifled due to the infliction of morals. There is a fine line in what is inhumane and moral to the standards of society; causing the advancement of gene therapy to be limited....   [tags: Biology Medical Biomedical Genetics]

From this a new technique has evolved called gene therapy. Gene therapy was discovered in the 1980’s a few years after researchers were already able to isolate specific genes from DNA.
