Origin of life in membraneless protocells
(PHYSorg.com Chemistry)

How life arose from non-living chemicals more than 3.5 billion years ago on Earth is a still-unanswered question. The RNA world hypothesis assumes that RNA biomolecules were key players during this time as they carry genetic information and act as enzymes. However, one requirement for RNA activity is that there are a certain number of molecules within close enough proximity to one another. This would be possible if RNA was contained within a compartment, such as membraneless microdroplets (coacervates). Researchers at the Max Planck Institute of Molecular Cell Biology and Genetics in Dresden and the Max Planck Institute of Biochemistry in Martinsried have shown for the first time that simple RNA is active within membraneless microdroplets, enabling a suitable environment for the beginning of life.
