This discovery led to the concept of the ribosome as a ribozyme, an RNA molecule with enzymatic properties. The catalytic center of the ribosome, known as the peptidyl transferase center (PTC), is ...

Ribosomal RNA (rRNA) is a component of the ribosomes, the cellular machinery responsible for protein synthesis. rRNA molecules, along with ribosomal proteins, form the structure of the ribosomes and ...

This enables the RNA polymerase (RNAP) and the ribosome to coordinate their functions and work together efficiently directly.
