We used the anaphase–telophase chromosome aberration and comet (Single Cell Gel Electrophoresis,
SCGE) assays to evaluate the genotoxic effects of copper sulphate (CS) and cobalt chloride (CC) chemicals
prepared in two concentrations (EC50, 2xEC50), using methyl methanesulfonate (MMS) as a positive control
and untreated cells as a negative control.
