Figure 4. The H4K16Ac modification can be identified on Y', but not on X elements.

Figure 4

A. ChIP analyses of H4K16Ac occupancy on Tel7L, which contains an X, but no Y' element. Precipitated DNA was quantified by real-time PCR using primer pairs covering the indicated positions. Error bars show standard deviations. B. ChIP analyses of H4K16Ac as in panel A, but analyzing different positions on Y' elements. C. High resolution map H4K16Ac using a DNA tiling array (Affymetrix) reveal that H4K16Ac is present on the Y' element, but absent from the X elements of chromosome 4 telomeres.
