Fig.l Cell-free assembly of nuclei from demebranated Xenopus sperm in a Drosophila embryo extract. Time course through sperm decondensation and nuclear formation monitored by phase-contrast microscopy. Incubation was at 24°C for the times indicated (a) 0 min incubation (b and c) 15 min (d and e) 20 min (f and g) 30 min (h-k) 45-50 min (l-p) 60-70 min. The bar in panel p designates 25 (im and applies to all panels.
