Ribosome

Name:
Ribosome
Detailed information:
A ribonucleoprotein, the smallest organized structure in the cell. Ribosomes occur in all cells including bacteria, fungi, algae, and protozoa. They are the central point of protein synthesis. They contain from 45 to 60% of ribonucleic acid (RNA), the balance being proteins. Ribosome crystals have been produced; in the electron microscope these appear as sheets of black dots, each sheet(one ribosome thick) containing hundreds of ribosomes in recurring groups of four.See Deoxyribonucleic Acid; Ribonucleic Acid.
