In situ nick translation of fixed mitotic chromosomes after HpaII or MspI digestion allows us to detect different DNA methylation levels along chromosomes. We used this technique to analyse the methylation levels of CCGG sites in the active and inactive X chromosomes of female human cells. In addition, we analysed the distribution of these sites with respect to the banding pattern. Our data show that the inactive X, as a whole, is more methylated than the active one and that CCGG sequences are… CONTINUE READING
