Abstract
Chromosomes sometimes break spontaneously, or breakage may be caused by a mutagenic agent, such as ionizing radiation or a chemical compound. Unlike normal chromosome ends, broken ends tend to join each other. Usually the broken ends rejoin; in other words, the break heals. However, a break may lead to a deletion or, if more than one break has occurred in a cell, to structural rearrangements of chromosomes. At least three different DNA repair systems may be involved in the joining of broken chromosome ends (cf. Bartram, 1980).
