(Phys.org)—Among other things, the egg is optimized to process the sperm genome. The cytoplasmic factors that make this possible also give the egg the ability to reprogram the nuclei from other kinds of cells if these nuclei ...
Cells have devised many structures for transporting molecular cargo across their protective borders, but the nuclear pore complex, with its flower-like, eight-fold symmetry, stands out. Monstrously large by cellular standards, ...
