Question

Quizplus · Accepted Answer

Scientists have not yet accomplished the formation of protocells that use DNA to direct the polymerization of amino acids. While researchers have made progress in synthesizing small RNA polymers by ribozymes, forming molecular aggregates with selectively permeable membranes, and abiotic synthesis of organic molecules, the origin of life is still a complex and unresolved topic of study.
