Simultaneous transcription & translation of a prokaryotic DNA
The figure shows an electron micrograph and its interpretation. DNA and strings of individual ribosomes attached to a single mRNA (polyribosome) are visible. The mRNA and RNAPol molecules are barely visible, and the protein polypeptides are too small to be seen.
