Journal ArticleDOI
Identification of genes that are associated with DNA repeats in prokaryotes.
TL;DR: A novel family of repetitive DNA sequences that is present among both domains of the prokaryotes but absent from eukaryotes or viruses is studied, characterized by direct repeats, varying in size from 21 to 37 bp, interspaced by similarly sized non‐repetitive sequences.
Journal ArticleDOI
