Germ line clones mutant for Rpp30
18.2 were immunostained for PCNA (red). DAPI is in blue. Magnifications: PCNA signal in a control or mutant nurse cell. Scale bar, 10 μm.
Germ line clones mutant for Rpp30
18.2 were immunostained for Brf (pol III) (red). DAPI is in blue. A Z‐projection of Brf staining is shown. The arrow points to Brf aggregates in a mutant chamber. Scale bar, 10 μm.
