At Jef Boeke’s lab, you can whiff an odor that seems out of place, as if they were baking bread here. But he and his colleagues are cooking up something else altogether: yeast that works with chunks of man-made DNA. Scientists have long been able to make specific changes in the DNA code.

Now, they’re taking the more radical step of starting over, and building redesigned life forms from scratch. Boeke, a researcher at New York University, directs an international team of 11 labs on four continents working to “rewrite” the yeast genome, following a detailed plan they published in March.

Their work is part of a bold and controversial pursuit aimed at creating custom-made DNA codes to be inserted into living cells to change how they function, or even provide a treatment for diseases. It could also someday help give scientists the profound and unsettling ability to create entirely new organisms.

The genome is the entire genetic code of a living thing. Learning how to make one from scratch, Boeke said, means “you really can construct something that’s completely new.” The research may reveal basic, hidden rules that govern the structure and functioning of genomes.

But it also opens the door to life with new and useful characteristics, like microbes or mammal cells that are better than current ones at pumping out medications in pharmaceutical factories, or new vaccines. The right modifications might make yeast efficiently produce new biofuels, Boeke says. Source: https://m.phys.org/

The human genome project and the study of the genetic markers contained within DNA has now brought to light the story of man’s origins and his journey across the planet. This National Geographic documentary follows Dr Spencer Wells as he retraces that incredible journey.
