The term "RNA World" refers to a hypothetical time in the evolution of life on earth in which catalytic RNA was the sole genetic material and in which the standard Watson-Crick pairing was the basis of genetic manipulation; a hypothesis that has been given a new lease on life due to the recent discovery of present-day RNA molecules that do indeed display catalytic activity.
Depending on when you last formally studied biology and genetics, you may still think of RNA as a simple messenger that is the intermediary between a gene's deoxyribonucleic acid (DNA) instructions and its protein end product.
