Near the edge of a chromosome's "black hole".

Abstract

The inability of current technology to determine contiguous sequence for highly repetitive regions means that centromeres fall within multi-megabase gaps, analogous to black holes from which no information escapes. However, high-resolution mapping of a human X-centromere border reveals a remarkable structure, including a gradient of alpha-satellite divergence up to the edge of the youngest and most homogeneous repeats.
