title: Methylation site within a facultatively persistent sequence in the macronucleus of Tetrahymena thermophila.
abstract: DNA methylation occurs at the adenines in the somatic macronucleus of Tetrahymena thermophila. We report on a methylation site within a DNA segment showing facultative persistence in the macronucleus. When the site is present, methylation occurs on both strands, although only 50% of the DNA molecules are methylated.
