Detailed explanation-1: -Answer and Explanation: Ribosomal RNA (rRNA) is described as the type of RNA that associates with proteins in order to create ribosomes.

Detailed explanation-2: -rRNA is a non-coding RNA that helps to form ribosomes, which are the protein-synthesizing organelle of the cell. rRNA when encoded are either small or large. These small and large rRNA’s combine with ribosomal proteins and once assembled in the proper location, serve as ribosomal subunits for protein synthesis.

Detailed explanation-3: -Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis-the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.
