Quizplus · Accepted Answer

In an RNA world, RNA would function both in information storage and for catalysis. This hypothesis suggests that RNA could perform both tasks due to its ability to form complex structures and catalyze chemical reactions as a ribozyme. DNA would not be present in the early stages of life as it requires enzymes for replication, whereas RNA could self-replicate with the help of ribozymes. The presence of proteins would come later in evolution.
