Regarding the tail moment, the observed variations are the
same as those seen in relation to the percentage of DNA present
in the tail. There was an increase of more than 100% and 200%
for 7.8 and 15.6 lg/L Cu, respectively (p < 0.05; n = 3–4), in cells exposed
for 6 h. Cells exposed for 24 h exhibited a tail moment 3
times higher in a concentration of 7.8 lg/L Cu than the control
group (p < 0.05, n = 3–4).
