A histone-free chromosome under the electron microscope

When certain proteins, especially histones, are
removed fromchromosomes, the chromosomal
skeleton becomes visible under the electron
microscope (1). Such a structure is surrounded
by numerous darkly stained threads. A higher
magnification (2) shows that this is a single
continuous thread. It corresponds to the DNA
double helix.
