COVER Illustration of a hypothetical yeast genome structure model encompassing all synthetic chromosomes (gold) completed to date (white, native chromosomes). One-third of the chromosomes in the yeast genome have now been designed and synthesized by the Synthetic Yeast Genome Project (Sc2.0). A three-dimensional model of the chromosomes was generated with the Hi-C method. An "envelope" (thick tube shapes) represents the population of chromosome-interacting molecules; translucent tips reveal a 30-nanometer fiber modeled inside. See page 1038.
