However, one shouldkeep in mind that, as discussed before, the repair process (hencerearrangement profiles) are also expected to depend on chromatinconformation and dynamics, so it is usually difficult, without aclear mechanistic framework, to attribute this correlation betweenbanding patterns and breakage occurrence to either a true damageprotecting effect in dense regions or a repair bias that would favorrearrangements in more open chromatin regions. This could indeedrather reflect the relative roles of slow and fast repair componentsof induced DSBs leading to chromosome aberrations. It should also be noted that, while nonrandom distributionsof DSBs are usually observed with high-LET radiation, several stud-ies using low-LET radiation showed no differences in DSB yields ordistributions in different parts of the genome
