ribosome
n 1: an organelle in the cytoplasm of a living cell; they attach
to mRNA and move down it one codon at a time and then stop
until tRNA brings the required amino acid; when it reaches
a stop codon it falls apart and releases the completed
protein molecule for use by the cell; "the ribosome is the
site of protein synthesis"

Ribosome - Wikipedia
Ribosomes ( ˈraɪbəzoʊm, - soʊm ) are macromolecular machines, found within all cells, that perform biological protein synthesis (messenger RNA translation) Ribosomes link amino acids together in the order specified by the codons of messenger RNA molecules to form polypeptide chains
Ribosome | Definition, Function, Formation, Role, Importance, Facts . . .
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
Ribosomes Function, Structure, and Facts - Science Notes and Projects
Ribosomes are macromolecular machines found in all living cells that synthesize proteins by translating messenger RNA (mRNA) Located in the cytoplasm, ribosomes either float freely or attach to the endoplasmic reticulum in eukaryotic cells
Ribosome - National Human Genome Research Institute
A ribosome is the cellular machinery responsible for making proteins There are many ribosomes in each cell, each made up of two subunits These two subunits lock around the messenger RNA and then travel along the length of the messenger RNA molecule reading each three-letter codon
Ribosomes: Definition, Structure, Functions, with Diagram
Ribosomes are cell structures present in large numbers in all living cells acting as the site of protein synthesis In prokaryotes, they float freely in the cytoplasm, while in eukaryotes they are free or remain bound to the outer membrane of the endoplasmic reticulum They are also found in the mitochondria and chloroplast of a eukaryotic cell
ribosome | Learn Science at Scitable - Nature
