In the middle of the 19th cent, Gregor Mendel performed his landmark experiments indicating that certain traits can be inherited and he proposed a discrete unit of inheritance that we now call a gene. Since then scientists have come to appreciate the gene and have focused on the link between genes and diseases.
Gene Therapy is a young and experimental procedure with goals to ultimately prevent diseases by changing the expression of a persons genes. However, there are factors that prevent the absolute success of this procedure, but scientists are continuing to work to find cures for genetic disorders and with technology improving will eventual have absolute success

In the past ten years, the issue of gene doping has become more prevalent in the athletic community. With the arrival of new technologies able to repair genetic disorders and other diseases and injuries in athletes, it is inevitable that other athletes would be willing to take advantage of this technology to enhance their own abilities. The World Anti-Doping Agency (WADA) currently defines gene doping as â€œthe non-therapeutic use of cells, genes, genetic elements, or of the modulation of gene expression, having the capacity to improve athletic performanceâ€. Gene doping would be used in a number of different ways, such as the increase in recovery rate of muscles or stronger joints and

Gene therapy is the transplantation of normal, healthy genes into cells in place of missing or defective ones in order to repair or replace the diseased causing cell, genes. How it works is correct the genetic disorders, like sickle cell, brain cancer and other cancerous cell and viral infections. Biotechnologist have found that there is still no quick rout to achieving this. Gene therapy is still at its experimental stages of treatment, but some of their findings have been promising.
The gene therapy starts with a virus. The Genetic engineers then extract the genetic coding from the virus, replacing it with a therapeutic gene that is designed to produce proteins that help fight

1. Is gene therapy really a realistic approach to curing diseases? Discuss a few recent trials on gene therapy to support your opinion.
Yes, gene therapy is an alternative medicine to cure diseases especially inherited diseases like muscular dystrophy, cystic fibrosis, cancer as well as heart disease. Gene therapy can give a promising result for a rare inherited disease. One of the examples is the disease that causes progressive blindness or choroideremia. This disease affected 1 in 50 000 people around the world in which currently doesn’t have any cure. However, after underwent therapy, patients show improvement in their vision as the particular gene (CHM gene- Rab escort protein 1) was

With dominant genetic disorders, it is only necessary for an individual to be affected by one autosomal dominant disorder. Another words, usually a child will only have one parent that has the disorder and when the parents conceive, the child then has a 50% chance of inheriting the mutated gene. Recessive genetic disorders are caused when an individual receives two defective genes, one from each parent. An example of a dominant genetic disorder is Neurofibromatosis. There are two types of NF, there is NF1, and NF2. I have Neurofibromatosis type 1, and with this an individual has neurofibroma tumors that grow on the nerve endings from on the outside of their body. NF type 2 is very uncommon

Everybody carries about half a dozen defective genes. Many don't know this, unless someone they know is affected by a genetic disorder.(1) The genetics of many diseases are passed from one generation to the next by inheriting a single gene, such as Huntington's disease. Many other diseases and traits are influenced by a collection of genes.(4) About one in ten people has, or will develop, an inherited genetic disorder. Approximately 2,800 specific conditions are known to be caused by defects, or mutations, in just one gene. Most of us don't suffer any harmful effects from our defective genes because we carry two copies of nearly all genes. In most cases one normal

Gene patenting: recent debate
Much of the debate around gene patenting in Australia has been prompted by the case of the BRCA genes. BRCA1 and BRCA2 are human genes that belong to a class of genes known as tumour suppressors. Mutation of these genes has been linked to hereditary breast and ovarian cancer. Patents for these genes are held by Myriad Genetics, an American company, which has granted Genetic Technologies exclusive rights to BRCA1 and BRCA2 testing in Australia.
In 2002-3, and again in 2008, Genetic Technologies sought to enforce its rights in relation to the BRCA genes in Australia, including through demands that public hospitals and other laboratories cease to offer the tests

The Viability of Gene Therapy for Hemophilia
Gene therapy is a vast field, and experimentation is being attempted for a broad range of diseases. Gene therapy for hemophilia is specifically more viable than gene therapy for other diseases, even though it has some fallbacks of its own. Researchers have found that specific viral vectors can be used in gene therapy for hemophilia. Over the years, scientists have created a large experimental base by usage of both animal and human models. They have also found that there are certain technical problems to be overcome, despite the advances that have been made.

EXAMINATION OF THE TAS2R38 GENE AND ITS SPECIFIC NUCLEOTIDE DIFFERENTIATIONS TO DETERMINE ABILITY TO TASTE PHENYLTHIOCARBAMIDE
Although humans are essentially genetically identical as a whole, there are some minute variances in our gene coding that allow for differences in our interactions with the world. These genetic modifications may have extensive detrimental effects, small effects, or no apparent effect at all. A few of these alterations can even affect our senses. In this lab, we examine how a discovery by a scientist gives us insight into how a relative dissimilarity between humans can affect the ability or inability to taste certain chemicals.

A knockout mouse is a genetically engineered mouse in which researchers have inactivated, or "knocked out," an existing gene by replacing it or disrupting it with an artificial piece of DNA. The loss of gene activity often causes changes in a mouse's phenotype, which includes appearance, behavior and other observable physical and biochemical characteristics. The resulting phenotypic change in the mouse can be used as an indicator for the gene’s normal role in mouse and, by extrapolation, humans. Developed in 1989 by Mario R.
