Quote by Sidney Altman
The RNA World referred to an hypothetical stage in the origin of life on Earth.

Summary
The quote suggests that the RNA World concept symbolizes a hypothetical phase during the emergence of life on our planet. This theory postulates that before the existence of DNA or proteins, RNA molecules played a crucial role in early biochemical processes. RNA molecules were thought to have the ability to store genetic information and catalyze chemical reactions, potentially serving as a bridge between simple organic molecules and more complex life forms. While still a hypothetical concept, the RNA World hypothesis provides insights into the evolution of life and the building blocks that may have led to the development of early organisms.
