A site and strand specific nuclease activity with analogies to topoisomerase I frames the rRNA gene of Tetrahymena.
Exposure of macronuclear chromatin from Tetrahymena thermophila to sodium dodecyl sulfate causes an endogenous nuclease to cleave the extra-chromosomal rDNA at specific sites. All cuts are single-strand cleavages specific to the non-coding strand. Three cleavages map in the central non-transcribed s...
