The potential power of gene therapy essay

Beware off-target effects Debra Mathews: Collins The ethical arguments against human germline engineering are significant. A most compelling one is that medical research should always seek to balance benefits and risks, with individuals who are participating in research giving fully informed consent. But the individuals whose lives are potentially affected by germline manipulation could extend many generations into the future.

Essay on the History of Gene Therapy: The rDNA molecules were first duplicated and grown in bacteria in Later split gene was discovered through the use of recombinant DNA technologies in Two independent techniques were developed in to determine the DNA sequences that contain genetic information.

This facilitated direct inspection of the genetic material and analysis of its functions. A strain of Pseudomonas bacterium was developed later in that could digest certain petrochemical.

These techniques lead to the launch of Humulin i. Recombinant DNA techniques were first used for the prenatal detection of sickle cell disease in The interaction between zinc and growth hormone gene was due to special DNA sequence in the growth hormone gene.

The progeny of the genetically altered mice inherited the new gene, to make them grow twice in size. Genes and Expression of Traits: Single gene associated mutation leads to genetic diseases. This would be corrected by single gene therapy, which is relatively easy as compared to multiple gene based traits or its interaction with environment.

Such diseases are called single gene defects. Most diseases have a mixture of genetic and environmental contributions. In disorders like Huntington or Tay-Sachs diseases, the influence of a single gene is so vast that the disorders are called genetic diseases.

The similar patterns of inheritance have been observed in various human diseases, and thus indicate gene associated diseases.

The disease due to molecular defects in non-enzyme proteins has also been observed. It is sickle cell anemia, in which an abnormal hemoglobin protein has been found. Many genetic diseases are due to changes in just a single gene, such as Adenosine deaminase ADA and purine nucleoside phosphorylase PNP enzyme deficiencies among human.

Disorders such as sickle cell anemia, familial hypercholesterolemia, polycystic kidney disease, Huntington disease, neurofibromatosis, Duchenne muscular dystrophy, cystic fibrosis, achondroplasia, hemophilia etc.

The prevalence of disease like Alzheimer and hemochromatosis has been influenced by genetics. Single gene traits vary in expression, depending on its interaction with other genes and environment.The potential power of gene therapy Most gene therapy for diseases such as cystic fibrosis and hemophilia has been designed only to ease, not to cure, the disease.

However, the delivery of functional copies of genes provides a potential method to correct a disease at its most basic level. Gene drive gives scientists power to hijack evolution and so they might choose gene therapy of somatic or germ cells.

One potential problem with gene editing is the occurrence of “off. Teachers and students around the world are encouraged to celebrate by participating in the American Society of Human Genetics' (ASHG) 14th Annual DNA Day Essay Contest! This contest is open to students in grades worldwide and asks students to examine, question, and reflect on important concepts in genetics.

Initial enthusiasm for gene therapy as a treatment modality was curtailed by the death of a patient participating in a dose escalation gene therapy trial in 12 While this was a trial to use gene therapy to correct a metabolic disease (ornithine transcarbamylase deficiency) and not a cancer trial, all gene therapy trials were revaluated.

Essay on Gene Therapy | Genetics

Essay on the Importance and uses of Gene Therapy for Human! Gene therapy is the treatment of disease by replacing, altering, or supplementing a gene that is absent or abnormal and whose absence or abnormality is responsible for the disease.

Gene therapy is unique in that it employs the genetic material, DNA, itself as the means of treatment. Gene Therapy Essay Words | 19 Pages.
