How far can genetic engineering influence those already living?

AI Thread Summary
The discussion centers on the potential for genetic modification in humans, particularly regarding the future of designer babies and the possibility of altering DNA in existing individuals. It highlights that while the DNA in dividing cells can change, many cells in the body are differentiated and no longer reproduce, which complicates the idea of altering one's DNA later in life. The conversation also touches on the role of undifferentiated cells, such as stem cells, which could be targeted for genetic changes. Additionally, ethical considerations surrounding genetic engineering are acknowledged, emphasizing the political and moral debates that influence the acceptance and regulation of such technologies.

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.

Thread 'I need help understanding this quote about recent Natural Selection'

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
