These scientists have gotten yeast cells to build arbitrary DNA. This is pretty scary because any DNA pattern can be created.
The yeast can build any DNA from a database such as the Human Genome project. From any DNA pattern on file, the DNA created by the yeast can then be dropped into a DNA-less cell and set in motion to start reproducing.
This means that your DNA (and mine) can be stored in a computer and sent somewhere else to be booted up into a cell that might one day become another person. Staggering. This will have major implications for pretty much everything having to do with genetics and molecular biology.
Yikes! Read more here.
