Mitochondrial localization of CCA-RNAs.
Cytoplasmic and mitochondrial fractions of HeLa cells were subjected to northern blot for (N)CCA-RNAs. Cytoplasmic tRNALysCUU and mitochondrial tRNAValUAC were analyzed as control cytosolic and mitochondrial RNAs, respectively. A single asterisk: a non-specific cytoplasmic band; double asterisks: the bands of potential precursor RNAs of nccaR-1.
