A DNA Segregation Module for Synthetic Cells

A DNA segregation module for bottom-up assembled synthetic cells is realized. It is based on DNA droplets that are engineered to segregate upon enzymatic or photocleavage inside giant unilamellar lipid vesicles (GUVs). The segregation kinetics is altered by the confinement, as confirmed by lattice-based numerical simulations. DNA segregation is further...
