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
通过核酸杂交程序对绿螈(Triturus viridescens)的重复DNA序列进行了研究。从未分级的绿螈DNA中酶促合成互补RNA。这种RNA与体细胞染色体和灯刷染色体的着丝粒区域都有强烈杂交。它也与沿染色体长度分散的其他位点结合。通过原位杂交证明了多个卵母细胞核仁中扩增的核糖体DNA。
