5-Methylcytosine is not detectable in Saccharomyces cerevisiae DNA

Abstract

We examined the DNA of Saccharomyces cerevisiae by both HpaII-MspI restriction enzyme digestion and high-performance liquid chromatography analysis for the possible presence of 5-methylcytosine. Both of these methods failed to detect cytosine methylation within this yeast DNA; i.e., there is less than 1 5-methylcytosine per 3,100 to 6,000 cytosine residues.
