How far can genetic engineering influence those already living?

In summary, the conversation discusses the potential for changing DNA in both current and future generations through genetic engineering. There are ethical considerations surrounding the use of this technology, particularly in regards to differentiating cells and targeting specific areas of the body.

So it's easier to change a clump of cells and designer babies will be part of the future... but what about people living now? Will I be able to change my DNA 20 or 30 years from now?

Thanks for any replies. :)

The DNA in every dividing cell in your body is subject to change, but I don't think that's what you mean.

Many cells in your body are differentiated- they have reached a terminal state, are executing a set genetic program and no longer reproduce (muscles, nerves, epithelial cells, endothelial cells). Other cells are undifferentiated- basal cells, stem cells in the marrow, etc. Those could be targeted, leading to new differentiated cells (epithelial cells come from basal cells, blood comes from the marrow, etc) with transgenes.

There are lots of political forces here at work in what is 'moral' and 'immoral' in genetic engineering.
 

1. How does genetic engineering affect an individual's health and well-being?

Genetic engineering can potentially improve an individual's health by correcting genetic defects or preventing the development of diseases. However, it can also have negative effects on an individual's health if not done properly, such as unintended consequences or triggering allergies. More research is needed to fully understand the long-term effects of genetic engineering on an individual's health and well-being.

2. Can genetic engineering be used to enhance physical and mental abilities?

Yes, genetic engineering has the potential to enhance physical and mental abilities by manipulating genes responsible for traits such as strength, intelligence, and memory. However, there are ethical concerns surrounding the use of genetic engineering for enhancement purposes, and more research is needed to fully understand the consequences of such modifications.

3. How can genetic engineering impact the diversity of species?

Genetic engineering can potentially reduce the natural diversity of species by creating genetically modified organisms (GMOs) that have the same genetic makeup. This can lead to a decrease in biodiversity and affect the balance of ecosystems. On the other hand, genetic engineering can also be used to preserve and restore endangered species by introducing desirable genes into their populations.

4. Are there any potential risks or dangers associated with genetic engineering?

Like any technology, genetic engineering carries potential risks and dangers. These include unintended consequences, such as creating new diseases or harming non-target organisms, as well as ethical concerns about playing with the genetic makeup of living beings. It is important for scientists to carefully consider and mitigate these risks before implementing genetic engineering technologies.

5. Can genetic engineering be used to extend the lifespan of humans?

While genetic engineering has the potential to manipulate the aging process and increase lifespan, it is currently not possible to accurately predict and control the complex mechanisms of aging. Therefore, genetic engineering is not currently a reliable method for extending human lifespan. More research is needed in this area before any definitive conclusions can be made.
