Ribosomal ribonucleic acid (rRNA) is the RNA component of ribosomes, the molecular machines that catalyze protein synthesis. Ribosomal RNA constitute over sixty percent of the ribosome by weight and are crucial for all its functions – from binding to mRNA and recruiting tRNA to catalyzing the formation of a peptide bond between two amino acids.
Ribosomal RNA is a molecule in cells that forms part of the protein-synthesizing organelle known as a ribosome and that is exported to the cytoplasm to help translate the information in messenger RNA into protein.
Ribosomal ribonucleic acid (rRNA) is a type of non-coding RNA which is the primary component of ribosomes, essential to all cells. rRNA is a ribozyme which carries out protein synthesis in ribosomes.
Ribosomal RNA (rRNA) is a type of stable RNA that is a major constituent of ribosomes. It ensures the proper alignment of the mRNA and the ribosomes during protein synthesis and catalyzes the formation of the peptide bonds between two aligned amino acids during protein synthesis.
All cells require ribosomes, the main building block of non-coding RNA known as ribosomal ribonucleic acid (rRNA). To create the large and small ribosome subunits, ribosomal RNA is translated from ribosomal DNA (rDNA). Table of Contents.

Ribosomes are made up of ribosomal proteins and ribosomal RNA (rRNA). In prokaryotes, ribosomes are roughly 40 percent protein and 60 percent rRNA . In eukaryotes , ribosomes are about half protein and half rRNA.
Ribosomal RNA (rRNA) molecules are the structural components of the ribosome. The rRNAs form extensive secondary structures and play an active role in recognizing conserved portions of mRNAs and tRNAs. They also assist with the catalysis of protein synthesis.
Ribosomal RNA Definition. Ribosomal RNA (rRNAs) are RNA molecules that are essential components of ribosomes. Ribosomes are the structural and functional units of protein synthesis in all living cells. In eukaryotes, there are three types of r RNA: 28S, 5.8S, and 18S. It carries out the instructions on messenger RNA during protein synthesis.
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures...
Definition. rRNA is part of ribosomes, serving as structural components and also catalyzing peptide bond formation. It's essential for protein synthesis in all living organisms.
