Ribosome
Are ribosomes tiny protein factories?
Ribosome is a tiny organelle that is the site of protein synthesis in the living cell. Ribosomes are complex, bead-like structures composed of about 40% protein and 60% ribosomal RNA (rRNA).
A ribosome is not a single piece. It is made up of two pieces or subunits that are a mix of protein and ribosomal RNA (rRNA). In eukaryotes, ribosomes contain four strands of RNA and are often attached to the membranes of the endoplasmic reticulum to form rough ER.
Build a Ribosome
Note: In the body, ribosomes are not built like how jigsaw puzzles are assembled. In fact, smaller and larger subunits of ribosomes are assembled to form the complete ribosome structure. The process is much more intricate and it's mediated by enzymes.
