Simple repetitive DNA sequences are transcribed in early embryonal stages of Xenopus laevis.
We have isolated and sequenced three cDNA clones from early embryonal stages of Xenopus laevis containing highly repetitive sequences. By means of poly A+ RNA hybridization we could show that simple repeats of the type AC/TG are ubiquitously transcribed in the ovary and in early embryonal stages of Xenopus laevis.
