The genomic DNA from all samples was obtained and
amplified at least twice on different days. The control and
treated samples for each experiment were individually amplified but developed together in the same agarose gel. Quantitative analysis was performed by comparing the percentage
appearance of each band for the control and treated samples. After eliminating the background, quantitative differences were studied using volume and percentage
parameters of the amplified band. Additionally the individual data were grouped together according to the following
criteria: bands of high molecular weight (>800 bp), bands
of intermediate molecular weight (500–800 bp) and bands
of low molecular weight (
