We created this series of three animations for the BBC to accompany the above article. This one focuses on RNA, and how it codes for proteins, which are essential for life. In the primordial soup, it may have been the first carrier of genetic information, as it is able to store information, replicated and catalyse reactions.
This one focuses on ATP, which is used to power every cell. Proton pumps create a concentration gradient, which forces protons through the ATP synthase motor, which turns ADP into ATP, storing energy inside them that can be transported around the cell and used where needed.
This one focuses on DNA, and how it assembles and replicates, allowing the storage and duplication of all the information needed to build an organism.
