Chapter 2, Problem 15RQ
Summary Introduction
To describe: The ‘Cambrian explosion’.
Introduction: The first living organisms that were originated are protocells, which are the membrane-bound cells that could reproduce. Ribonucleic acids are formed, which mediate the processing of messenger RNA, which is the earliest self-replicating molecule. Then, the membrane vesicles are formed by the spontaneous process.
