For example, Schantz et al demonstrated that sensitivity to chromatid breaks of lymphocytes treated with bleomycin was one such marker. For example, Chinese hamster ovary cells exposed to DU exhibit lower cell viability, depressed cell cycle kinetics, and increased sister chromatid exchanges, micronuclei, and chromosomal aberrations after DU exposure (Lin et al. Through a process of 'crossing over', the segments of non-sister chromatids of a homologous pair of homologous dyads are exchanged. |
