title: Simple repetitive sequences in the genomes of archaebacteria.
abstract: Stretches of simple sequences poly(dG-dT).poly(dC-dA), poly(dG-dA).poly(dC-dT), poly(dG).poly(dC) and poly(dA).poly(dT), the occurrence of which is a characteristic feature of eukaryotic genomes, are found in the genomes of archaebacteria Halobacterium halobium and Sulfolobus acidocaldarius. In S. acidocaldarius these sequences constitute a considerable portion of the genome; they belong to a class of repetitive sequences dispersed throughout the genome, being transcribed and found in RNAs of different lengths.
