Ribosome - Wikipedia
The ribosome (/ ˈ r aɪ b ə ˌ s oʊ m, -b oʊ-/) is a complex molecular machine, found within all living cells, that serves as the site of biological protein synthesis (translation). Ribosomes link amino acids together in the order specified by messenger RNA (mRNA) molecules.

Ribosome: Ribosome, particle that is present in large numbers in all living cells and serves as the site of protein synthesis. Ribosomes occur both as free particles in prokaryotic and eukaryotic cells and as particles attached to the membranes of the endoplasmic reticulum in eukaryotic cells. The small

A ribosome is a molecule consisting of two subunits that fit together and work as one to build proteins according to the genetic sequence held within the messenger RNA . Using the mRNA as a template, the ribosome traverses each codon, pairing it with the appropriate amino acid.

Ribosome | definition of ribosome by Medical dictionary
ribosome A spherical cell ORGANELLE made of RNA and protein which is the site of protein synthesis in the cell by linking amino acids into chains. Ribosomes may be free or may be attached to the endoplasmic reticulum. During translation, ribosomes attach to MESSENGER RNA molecules and travel along them, synthesizing polypeptides as they go. ribosome

Ribosome: a micro-machine for manufacturing proteins A ribosome is basically a very complicated but elegant micro-‘machine’ for producing proteins. Each complete ribosome is constructed from two sub-units. A eukaryotic ribosome is composed of nucleic acids and about 80 proteins and has a molecular mass of about 4,200,000 Da.
Eukaryotic ribosome (80S) - Wikipedia
Two 40S ribosomal proteins (RACK1 and rpS6) have been implicated in signaling: RACK1, the receptor of activated protein kinase C (PKC), is an integral component of the eukaryotic ribosome and is located at the back of the head, in proximity of rpS17. It links signal-transduction pathways directly to the ribosome (reviewed in ).
