Jefferson scientists use zebrafish to show effects of ionizing, UV radiation differ in development
...A. When the fish were exposed to UV light, the DNA formed "crosslinks" in which two thymine bases form on the same strand next to each other. The cell uses entirely different repair mechanisms to fix both types of damage. The Jefferson team performed a microarray analysis to confirm their findings.
