Spacer dna

spacer DNA

(Science: molecular biology) The dNA sequence between genes. In bacteria, only a few nucleotides long. In eukaryotes, can be extensive and include repetitive DNA, comprising the majority of the dNA of the genome. The term is used particularly for the spacer DNA between the many tandemly repeated copies of the ribosomal RNA genes.
