ABSTRACT
Nuclear reconstitution around Lambda DNA in a cell-free system from Xenopus eggs involves distinct steps at ultrastructural level. First, Lambda DNA polymers were induced to form chromatin-like structures with the proteins in egg extracts. Then, along with membrane vesicles and nuclear pore components attached to them to assemble double nuclear membranes, these chromatin-like structures underwent variations from condensation to decondensation, simultaneously. It is different from the nuclear reconstitution induced by chromatin in that, while membrane vesicles were attaching to the chromatin-like structures to fuse each other, the assembly of nuclear pore complexes occurred practically.
