Ribosomal RNA: Ribosomal RNA (rRNA), 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 (mRNA) into protein. The three major types of RNA that occur in cells include rRNA, mRNA, and

Ribosomal ribonucleic acid (rRNA) is the RNA component of the ribosome, and is essential for protein synthesis in all living organisms. It constitutes the predominant material within the ribosome, which is approximately 60% rRNA and 40% protein by weight, or 3/5 of ribosome mass.

ribosomal RNA (or rRNA) is a part of the ribosomes usually found on the Endoplasmic Reticulum. Hope this helps! rRNA helps build the proteins.

rRNA: Ribosomal RNA, a molecular component of a ribosome, the cell's essential protein factory. Strictly speaking, ribosomal RNA (rRNA) does not make proteins. It makes polypeptides (assemblies of amino acids) that go to make up proteins.. A tiny particulate structure located in the cytoplasm of the cell (outside the nucleus), the ribosome is composed of two subunits, one larger than the other...

en.wikipedia.org/wiki/16S_ribosomal_RNA

16S ribosomal RNA (or 16S rRNA) is the component of the 30S small subunit of a prokaryotic ribosome that binds to the Shine-Dalgarno sequence. The genes coding for it are referred to as 16S rRNA gene and are used in reconstructing phylogenies, due to the slow rates of evolution of this region of the gene.

The ribosome itself is highly complex. It is made up of dozens of distinct proteins (the exact number varies a little bit between species) as well as a few specialized RNA molecules known as ribosomal RNA (rRNA). Note – these rRNAs do not carry instructions to make specific proteins like mRNAs.

Transfer RNA along with ribosomes read the mRNA codons and produce a polypeptide chain. The polypeptide chain undergoes several modifications before becoming a fully functioning protein. Ribosomal RNA (rRNA) is a component of cell organelles called ribosomes. A ribosome consists of ribosomal proteins and rRNA.

Ribosomal ribonucleic acid (ribosomal RNA or rRNA) helps to form the ribosome itself. Unlike messenger RNA (mRNA), it does not transmit genetic information. Instead, it combines with proteins to create a structure that systematically transforms mRNA into proteins. The central dogma of cellular biology is that DNA is transcribed into RNA, which is translated into proteins.
