Ribosomes
All living cells contain ribosomes, tiny organelles composed of approximately 60 percent ribosomal RNA (rRNA) and 40 percent protein. However, though they are generally described as organelles, it is… More »

Ribosomes - Protein Construction Teams ... When you need to make proteins, you look for ribosomes. Ribosomes are the protein builders or the protein synthesizers of the cell. They are like construction guys who connect one amino acid at a time and build long chains.

Ribosome - Wikipedia, the free encyclopedia
Ribosomes ( from 'ribo nucleic acid and "Greek: soma ' ( meaning body)" ) are complexes of RNA and protein that are found in all cells with nuclei. Ribosomes from bacteria, archaea and eukary...

Ribosomes are the sites where the cell assembles proteins according to genetic instructions. A bacterial cell may have a few thousand ribosomes, although a human cell has a few million. Cells that have high rates of protein synthesis have a particularly great number of ribosomes.

Structure of Ribosomes ... Ribosomes are cytoplasmic granules composed of RNA and protein, at which protein synthesis takes place. They were first observed by Palade in the electron microscope as dense particles or granules. Upon isolation, they were shown to contain approximately equal amounts of RNA and protein Label.

Ribosomes consist of one large unit and one small unit. Half of the eukaryotic ribosomal weight comes from RNA. The ribosome contains a groove that guides the polypeptide chain and another groove that holds the mRNA molecule.
