Context examples:
A cellular response that is characteristic of apoptosis is fragmentation of the nuclear genome to create a nucleosomal ladder.

Studies have linked a high rate of sperm DNA fragmentation to infertility.

DNA binding by AIF stimulates chromatin condensation, and DNA fragmentation, perhaps through recruitment of nucleases.
(AIF Pathway, NCI Thesaurus/BIOCARTA)
Mannosylerythritol lipid activates protein kinase signal cascades, resulting in cell differentiation, condensation of chromatin, DNA fragmentation, G1 phase cell-cycle arrest, and apoptosis of tumor cells.

Everyone knows habitat loss is bad for animals, but there's been a longstanding debate about fragmentation – the arrangement of remaining habitat, said co-corresponding author Matt Betts of the OSU College of Forestry.
(Forest fragmentation hits wildlife hardest in the tropics, National Science Foundation)
Fragmentation changes how ecosystems function, reduces the amounts of nutrients retained and the amount of carbon sequestered and has other deleterious effects.
(Shrinking habitats have adverse effects on world ecosystems, NSF)
These structural changes (almost like a noodle snaking through the heart) lead to an appearance of mitochondrial fragmentation when imaged by conventional electron microscopy.

The chemically modified nucleotides that interfere with protein-nucleic acid complex formation can be identified by fragmentation and electrophoretic analysis of the DNA isolated from the complexes.
(Chemical Interference, NCI Thesaurus)
In the presence of the antibiotic, the fast-swimming species became much slower and formed aggregates, while the normally aggregated species shifted in structure to form even larger colonies, with less fragmentation.
(Impacts of low-dose exposure to antibiotics unveiled in zebrafish gut, National Science Foundation)
Apoptosis was found to be dependent on caspase activity because the pan-caspase inhibitor benzyloxycarbonyl-Val-Ala-Asp(OMe)-fluoromethylketone blocks cephalostatin 1-mediated DNA fragmentation.
