| Popis: |
Nucleosome positioning on linear polyomavirus DNA was evaluated by Fourier transform analysis of data obtained by electron microscopy visualization of reconstituted nucleosomes after photoreaction with trimethylpsoralen. Results show a non random nucleosome positioning and this implies that the histone octamer discriminates among various nucleotide sequences also in the very simple model system adopted in this study. This recognition process appears rather complex because of the limited correlation between nucleosome distribution and DNA curvature, suggesting that other interactions could play a role. |
