Glutaraldehyde-fixed chromatin fibers. Leuba et al. The 30 degree view of inclination is to make it easier to see that there are nucleosomes of double the height of other nucleosomes in the same fiber. Leuba et al. It is possible to see the linker DNA between the nucleosomes in the SFM images.
Height is encoded in color.
Leuba et al. Simulated and experimental SFM images of native chromatin fibres. The computer-generated image of a model chromatin fibre. The linker DNA is assumed to be straight between nucleosomes. The length of the linker DNA varies between 51 and 73 bp, which is determined using a uniform deviate random-number algorithm.
