15.siFor the first time ever, scientists have constructed a complex chromosome from scratch, a breakthrough they hope will lead to further progress in the development of new medicine and biofuels. According to the Guardian, the accomplishment is the result of seven years of work by international research teams in New York University and Edinburgh University. It was declared a success after the chromosome – originally found in brewer’s yeast – was transplanted into other yeast cells and continued to grow normally. Eventually, all the yeast cells ended up carrying the artificial chromosome. “They behave almost identically to wild yeast cells, only they now possess new capabilities and can do things that wild yeast cannot,” wrote NYU project leader Jef Boeke in the journal Science.
