Ribosomal RNA (rRNA) | Definition & Function | Britannica
网页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 are rRNA, mRNA, and transfer RNA (tRNA).
Ribosomal RNA - Wikipedia
网页Ribosomal RNA is transcribed from ribosomal DNA (rDNA) and then bound to ribosomal proteins to form small and large ribosome subunits. rRNA is the physical and mechanical factor of the ribosome that forces transfer RNA (tRNA) and messenger RNA (mRNA) to process and translate the latter into proteins.

Ribosomal RNA (rRNA): Definition & Function - Biology Dictionary
网页2019年10月4日 · 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 ribonucleic acid Definition and Examples - Biology …
网页2021年7月21日 · Ribosomal ribonucleic acid (rRNA) is a ribonucleic acid that, together with the ribosomal proteins, makes up the ribosome. Ribosomal RNA does not carry the code in making proteins. Rather, it forms the two subunits (i.e. large subunit and small subunit) of a ribosome.
