Description

Transmission electron micrograph showing part of a decondensed mitotic chromosome. The residual protein 'scaffold' (at bottom) is surrounded by a 'halo' of DNA loops 20 to 24 micrometers long. The entire chromosome is seen in the grouped CIL image 11021.

Technical Details

Micrograph from J.R. Paulson and U.K. Laemmli (1977) Cell, 12:817-828, and republished with permission as Figure 131 from Chapter 4 (Nucleus) of 'The Cell' by Don W. Fawcett M.D. This image is the enlarged inset panel from CIL:11021 in this image group.
