Eukaryotic Ribosome: proteins are blue and rRNAs are yellow and orange. Green is active site (where charged tRNA bind)

polysome.gif
Electron micrograph of a polysome: one mRNA strand (faint horizontal line) with many individual ribosomes attached (dark blobs). The newly synthesized polypeptide chains (proteins) can be seen as irregularly shaped extensions from the ribosomes.

POLYSOMES: The numbered ribosomes are shown tightly bound to a single mRNA strand at the core, with each mRNA making its own protein. The two major subunits of each ribosome are blue and yellow. The nascent protein chains being cranked out in close proximity to each other are green and red.


... and several other interesting and useful animations.





Not all DNA is transcribed... in fact, only about 1% of the 3 billion bases of information


And not all that is transcribed is translated...
