Fig. 4From: Simple and fast quantification of DNA damage by real-time PCR, and its application to nuclear and mitochondrial DNA from multiple tissues of aging zebrafishDNA damage measured within a nuclear and b mitochondrial DNA from different tissues of zebrafish of different ages. Error bars indicate standard deviation of three replicate measurements from the same DNA, for each of which there were three replicates of the PCR. Significance (in comparison to 5 months using a two-tailed t test): *p < 0.05; **p < 0.01; ***p < 0.001Back to article page
