Fig. 3. Meiotic time-course experiment in the rec14 mutant. Nuclear spreading and DAPI staining were carried out in a time-course of strain ED6. (A) Electron micrograph of a silver-stained class I nucleus. Arrowheads indicate short linear elements, the arrow points to the spindle pole body; `n' is the nucleolus. (B) Two class IIa nuclei. The nucleus on the left-hand side shows a regular network, the nucleus on the right-hand side has a `moth-eaten' network. (C) Short bundles in a class IIb nucleus. (D) Class III nucleus bearing single, long linear elements. Bar, 1 µm. (E) Quantitation of the different classes. (F) Timing of cytological events as followed by DAPI staining.
