Clastogenic

Clastogenic (pronounced /klæstəˈdʒɛnɨk/, US dict: klăs′·tə·jĕn′·ĭk) is an adjective that describes the ability of an agent or process to act as a clastogen—an agent or process giving rise to or inducing disruption or breakages of chromosomes.

Biology

Clastogenic in biology is a term which refers to an agent or process giving rise to or inducing disruption or breakages, as of chromosomes.

Illustrative sentence: "This leads to the conclusion that a chemical that fails to induce a significant response in an in vitro clastogenicity assay is unlikely to be clastogenic in vivo, in bone marrow assays."^[1]

Clastogens are mutagens which cause chromosome effects including breaks, rearrangements and changes in number.

Geology

Clastogenic in volcanic eruptions is a term which refers to an agent or process giving rise to or inducing disruption of the type of ejecta.

Illustrative sentence: "The complex features of this eruption can be explained by rapid deposition of coarse pyroclasts near the vent and the subsequent flowage of clastogenic lavas which were accompanied by a high eruption plume generating pumice falls and/or pyroclastic flows."^[2]
