Polyadenylated mitochondrial tRNAs are rapidly degraded after EtBr removal. Northern blots probed for mitochondrial tRNASer(UCN) or tRNALeu(UUR) as indicated, in wild-type 143B cybrid cells treated with 2.5 or 5 μg/ml EtBr for the indicated times, then allowed to recover in the absence of the drug as shown. Where shown, 5S rRNA was used as a loading control. RNA sizes (in nt) were extrapolated from the migration of mature tRNASer(UCN) (72 nt), 5S rRNA (121 nt) and ND3 mRNA (>345 nt).
