Scientists discover role of enzyme in DNA repair
... ribosomal genes, as a substitute. They attached a green
fluorescent protein to Polymerase I, a key component in the machinery that transcribes these genes, and were able to visualize the activity of this enzyme using microscopy. They then used a particular laser attached to the microscope to introduce DNA...
