Formation of protobionts that use DNA to direct polymerisation of amino acids. Explanation: • Scientists have successfully demonstrated the abiotic synthesis of small RNA polymers and polypeptides in the laboratory. • They have also observed the formation of molecular aggregates with selectively permeable membranes, such as microspheres, liposomes, and coacervates. • However, the formation of protobionts that utilize DNA to direct the polymerization of amino acids,essentially protocells with a fully functional genetic system and protein synthesis machinery,has not been achieved yet.
