Human Manipulation Of Genetic Transfer Essay

Gene therapy is a very controversial topic that has been discussed in the last five years and is being heavily studied to help cure cancer. Gene therapy is a technique aimed at treating genetic disorders by introducing the correct form of the defective gene into the patient’s genome (Dunlop et al., 2010).

Human gene therapy is a procedure that is currently being used to help fight diseases with no known cures. Gene testing removes a gene that causes a disease and replaces it with a healthy copy of that gene. By placing a healthy copy of the gene inside the patient’s body, that gene can help fight any diseases, such as different forms of cancer, inherited disorders, immune system discords or viral infections (AIDS). Once inside the cell, the genes produce what the patient lacks, it kills the diseased cells and it activates cells in the immune system.

Twenty five years ago Genetic Engineering was a scene from an unrealistic invention on a scene from a science fiction movie. However, recent scientific advancements, genetic engineering, is becoming more of a reality rather than a fantasy. Genetic Engineering was once an actually impractical thought, today it is a prominent issue around the world. The most controversial subject of genetic engineering deals with the impact that manipulation of humans will have on earth. Genetic engineering of humans will negatively affect the world in the following ways; social issues, violation of human rights, discrimination, religious objections and medical concerns.

Humans have been manipulating genetic transfer for over 10,000 years since our hunter- gatherer ancestors began to settle in one place and started farming and planting crops. Those humans observed and chose organisms from natural selection to select and breed organisms that showed characteristics desired by them and this began the process of selective breeding. Selective breeding favours recessive alleles that do not persist in wild populations. Selective breeding is a process of increasing the frequency of rare and recessive alleles so that they appear in homozygous form. This has the effect of eliminating the alleles for wild type from the population and the process of domestication has become irreversible. The domestic species has become dependent on humans for their survival. It is from these domestic species that humans have selected and breed favourable genetic traits for their benefit, be it higher yield in plant crops, sweeter tasting fruit, and more milk from dairy cows or ease of handling stock, selective breeding continues to be used today.

Gene therapy is an experimental technique that is used to prevent disease. For future reference, this technique may treat disorders. It may add or remove genes to get rid of a genetic disorder. Gene therapy is a heavily debated subject. There are very respectful points on both sides of this debated topic. The pro side believes that gene therapy is the best thing that is happening to our society. However, opposers of gene therapy believe that people should refrain from proceeding with this biological advancement and it is ethnically incorrect.

Gene therapy: Is a treatment method that involves the manipulation of an individual's genetic makeup. A form of therapy that attempts to fix the defective gene which is causing the disease.

Humans have been able to use the principles of DNA replication, gene transfer and gene expression (as observed in nature) as tools to manipulate specific genes towards preferred outcomes. An advantage of being able to manipulate genetic therapy is the ability to eliminate/cure genetic disease/disorders with otherwise no other cure. Humans are able to remove the genes causing the genetic disorder from the gene pool of populations, allowing organisms to live longer and healthier lives. Two ways of manipulating genetic transfer which will be explored further in this report are selective breeding and gene therapy.

Some people may wonder what gene therapy is. Gene therapy is the replacing of defective or missing genes with normal genes in order to cure the disorder. In the future, this technique may be used to prevent or treat a disorder by inserting

Gene therapy is the insertion of normal or genetically altered genes into cells to replace defective genes. The gene is usually inserted into

Gene therapy is a method involving DNA to treat or prevent disease. It is the insertion of a corrected gene into an organism’s cell to mask the presence of the dysfunctional gene, instead of surgery or using drugs. Put simple, gene therapy is the process of using DNA as a drug. Generally, a vector (‘delivery vehicle’) is used to go to the cells where it is needed and deliver a gene, if this is successful, the cell will then be able to produce a functional protein to treat or prevent the disease. Since the gene causing CF was discovered, it is now possible to attempt gene therapy to

On the other hand, genetic engineering can also be a great benefit as through gene therapy, genetic diseases can be prevented and quite possibly being wiped from existence. Another benefit of genetic engineering is that it can also allow infertile couples to have a baby but to do this would require the genetic information of a surrogate alongside the couple’s genetic information [12]. This could result in many complications which is why there is a great controversy on this matter. Although cloning is known by a plethora of people, whereas the minority of the population knows of genetic engineering which brings up the question, what is genetic engineering?

There are two types of gene therapy; germline gene and somatic gene therapy. Germline gene therapy is considered to be a safer option for humans. This method makes changes to the gamete cells that are used in the reproductive process thus, the functional genes need to be inserted into the chromosomes. Somatic gene therapy is when genes are transferred to body cells by inserting vectors into a person’s body. There are three things that gene therapy can do; replace a mutated gene that causes a disease with a healthy gene, deactivate a mutated gene that is not able to function properly, or introduce a new gene into the body to prevent diseases. There has been a clinical trial in the past where over 3000 people were treated with gene therapy and the results were good however, this treatment method has serious health

Gene therapy is an experimental form of treatment, where normal genes are placed into missing or defective ones in order to correct or alter genetic disorders. In other terms, it is the therapeutic delivery of nucleic acid polymers into a patient 's cells as a drug to treat disease (Gennady, 2015). After many attempts at modifying human DNA by nuclear gene transfer as well as insertion of human DNA in the nuclear genome, the first successful gene therapy was in 1990 where it was used to cure four-year-old Ashanti DaSilva who had Severe Combined Immune Deficiency (IDF 2013 National Conference). Since then gene therapy has been used to cure and treat serious diseases such as Chronic Granulomatus Disorder, Hemophilia, and a wide variety of Cancers, and other genetic and acquired diseases (American Society of GENE & CELL THERAPHY, online).

Gene therapy is a relatively new technology that has shown some promising results. Such as the drug called Strimvelis that is used to help children with severe combined immunodeficiency, a disease that leaves infants with little to no protection against viruses, bacteria, fungi, and other potentially harmful things. It appears to be a cure carried out through a genetic pair. Strimvelis was tested on 18 children, starting 15 years ago, all of whom are still alive today. Gene therapy is used to inject genes into a person’s cells and tissues in order to treat a disease, as well as hereditary diseases where an abnormal allele is replaced with a fully functional allele. The carrier, called a vector, is used to transport the normal gene to the target cells. The most common type of vector are viruses that have been genetically altered to carry human DNA. Scientists have been trying to control the way the viruses have evolved encapsulating and delivering their genes to normal cells in a pathogenic way by manipulating the viral genome to remove disease-causing genes and inserting healthy ones. Theoretically, it is possible to transform either the cells of the body (somatic) or the cells of the sperm, ova, and their precursors (germline). All of the gene therapy experiments so far on humans have been directed to somatic cells, because germline experiments have been remaining controversial. Somatic gene therapy is split into two broad categories: ex vivo (cells are modified outside of the body then returned back again) or in vivo (genes are changed in cells while still located inside of the

With our current society rapidly advancing in both the technological and medicinal world, many new treatments have been born that can be used to treat genetic conditions that regular antibiotics and surgeries simply have no positive or progressive effect. Gene therapy is when a newly developed gene is transferred, or introduced, to an already existing gene, it is the attempt to treat one’s genetic disorder at the molecular level and could significantly improve the human population and provides hope to people with disabilities. Gene therapy goes straight to the source and alleviates symptoms of the disorder. The gene receiving this new development is in some shape or form, mutated, or defective. If the gene therapy is a
