Genetically Engineered Material
Transcript of Genetically Engineered Material
Bryce Timm The controversy of using GEMs in human subjects It is also thought that genetic engineering could be used to change physical appearance, metabolism, and even improve mental faculties like memory and intelligence in the future. the use of gene therapy to design children will be spread through what he calls “free market eugenics”. Wealthy families will design their child with genetic advantages. T his use of gene therapy will mean wealthy families pass down enhanced traits to their children, potentially disadvantaging poorer families that can't afford the technology. Potential Issues What is a GEM? Controversy
The belief that every fetus has an right to remain genetically unmodified
and the belief that every child has the right to be born free from preventable diseases. Genetic engineering is any process by which genetic material (the building blocks of heredity) is changed in a way to make possible for the production of new functions.
Scientists have discovered that cells have certain kinds of enzymes that take DNA molecules apart and put them back together again.
Bacteria is often used, such as in the creation of Insulin. Humans with diabetes cannot make their own insulin in the Pancreas, therefore bacteria is used to perform the function. Human genetic engineering is already being used on a to allow infertile women with genetic defects to have children. Healthy human eggs from another mother are used. A child made this way has genetic information from two mothers and one father. The changes made will likely be passed down from generation to generation, which means they are a permanent change to the human genome. It could cure genetic diseases like cystic fibrosis, and increase the immunity of people to viruses.

Here the new gene is put in after the person has grown up and already become ill, so any new gene won't be passed on to their children. If we were all to undergo genetic modification this could limit our genetic diversity ... there could be a danger that our gene pool diminishes and that as a population we become wiped out by a disease threat. http://www.brighthub.com/science/genetics/articles/22211.aspx www.scienceclarified.com
