The 4th CIMoS Seminar <br>Artificial Cell Viewed as Molecular System

We have been studying construction of an artificial cell as a molecular system through a constructive approach [1]. Recently, we succeeded in achieving a giant vesicle (GV)-based protocell in which replication of DNA proceeded. When a precursor of the membrane lipid was added to the dispersion of this protocell, the giant vesicle (GV) with amplified DNA grew and divided to produce a new GV in which the amplified DNA was partitioned. The GV-based protocell satisfied the requirement for an artificial cell [2]. The recent results related to this topic will also be presented.
