What role do ribozymes play in biological systems?

Ribozymes play a crucial role in biological systems by catalyzing biochemical reactions. These are RNA molecules that possess catalytic activity, enabling them to facilitate chemical reactions without the need for protein enzymes. This unique property demonstrates the versatile nature of RNA beyond its traditional role in carrying genetic information.

Ribozymes are involved in various cellular processes, including RNA processing and the catalysis of peptide bond formation during protein synthesis. Their ability to promote reactions suggests that RNA may have been integral to early life forms, possibly supporting the hypothesis of an "RNA world" in the evolution of life.

The other roles mentioned, such as serving as structural components, storing genetic information, or exclusively assisting in protein synthesis, are primarily attributed to proteins or DNA. While ribozymes contribute to protein synthesis, they are not limited to this function alone, further emphasizing their significance as catalysts in biochemical reactions across different biological systems.
