Abstract
Radiation-induced chromosome aberrations were used as biomarkers to co mpare G(0), mid-G(1), and methotrexate (MTX)-arrested lymphocytes. The ratio of chromosome-type to chromatid-type aberrations in MTX-arreste d cells was consistent with that predicted when postreplicative chromo somes are exposed to ionizing radiation and supports the premise that MTX arrests cells in late S/G(2) of the cell cycle.
