The DNA methylase activity present in embryos and cultured cells of Xenopus laevis resembles DNA methylase from mammalian tissues. Little or no activity is found in mature germinal vesicles, though nuclear activity rises rapidly after fertilization. This rise may result in part from a relocation of cytoplasmic enzyme.
