Figure 4: Protein turnover and DNA stand breaks in mussels exposed to nAg with different coatings. Mussels were exposed to 50 μg/L nAg with different coatings for 96 h. The levels of ubiquitin protein tagging (a) and DNA stand breaks (b) were determined in the digestive gland (DG) and gills. indicates significance from the controls.
