Partial DNA unwrapping enables easier access of DNA-binding factors to their target sites and thus may provide a dominant pathway for effecting rapid and robust access to DNA packaged into chromatin. Indeed, a recent high-resolution map of distances between neighboring nucleosome dyads in \\emph{S.cerevisiae} shows that at least 38.7\\% of all nucleosomes are partially unwrapped.
