The statement is true because RNA possesses unique properties that allow it both to replicate itself and to act as a catalyst in various biochemical reactions.

One of the key roles of RNA is in the process of self-replication, particularly in certain viral genomes and in some RNA-based life forms proposed by the RNA world hypothesis. This hypothesis suggests that early life may have been based on RNA capable of serving as both genetic material and a catalyst before the evolution of DNA and proteins. Certain RNA molecules, known as ribozymes, can catalyze chemical reactions, akin to enzymes, which further supports the idea of RNA's catalytic abilities.

These ribozymes can facilitate a variety of biochemical reactions, including those needed for the synthesis and processing of RNA itself, and potentially other reactions within cellular processes. This dual functionality of RNA as both a genetic carrier and a key player in biochemical catalysis highlights its remarkable versatility and importance in molecular biology.

Therefore, the assertion that RNA is capable of both self-replication and catalyzing reactions is well-supported by current scientific understanding.
