Reverse engineering 3-D chromosome models for individual cells

Genome analysis can provide information on genes and their location on a strand of DNA, but such analysis reveals little about their spatial location in relation to one another within chromosomes—the highly complex, three-dimensional ...

Researchers build artificial chromosome

Biotechnologists at Delft University of Technology have built an artificial chromosome in yeast. The chromosome can exist alongside natural yeast chromosomes, and serves as a platform to safely and easily add new functions ...
