title: Chromosomal localization of repetitive DNA in the newt, Triturus.
abstract: The repetitive DNA sequences of the newt, Triturus viridescens, have been studied by nucleic acid hybridization procedures. Complementary RNA was synthesized enzymatically from unfractionated newt DNA. This RNA hybridized strongly to the centromeric regions of both somatic and lampbrush chromosomes It also bound to other loci scattered along the lengths of the chromosomes The amplified ribosomal DNA in the multiple oocyte nucleoli was demonstrated by in situ hybridization
