Synthetic biology has come a long way in recent years. In the last two decades alone, scientists have been able to go from synthesizing the genome of a relatively small virus, Hepatitis C, to creating what researchers refer to as the "first synthetic cell" from a unicellular organism. Yet until recently, researchers had been incapable of constructing one of the most emblematic symbols of our own genetic makeup: the eukaryotic chromosome. Now, a team of scientists has announced that the age of the synthetic chromosome is upon us, as a study published in Science today reveals how the group was able to construct a yeast chromosome from scratch — an experiment that allowed the team to make fully functional "designer yeast."
