Scientists have built a custom chromosome -- a package of genetic material assembled entirely from synthetic DNA. This engineered chromosome belongs to yeast, but experts say it can help them understand how genes work in humans as well. And it could help make these tiny living factories better at producing everything from medicines to biofuels. VOA’s Steve Baragona tells us students were key to the project.
