Spacers are bits of DNA that are interspersed among these repeated sequences. Generally, SSU and LSU rDNA genes were applied to higher taxonomic level delineation, whereas ITS was used for species or genus resolution. The terms intergenic spacer (IGS) or non-transcribed spacer (NGS) are used particularly for the spacer DNA between the many tandemly repeated copies of the ribosomal RNA genes.

Nukleosomen haben funktionelle Relevanz bei der Bildung von Heterochromatin, beim Gene silencing oder bei der Aufspiralisierung der DNA vor der Mitose. A related consideration is whether the arm is cleavable (i.e., whether the linkage can be reversed or broken when desired). The doubly bound DNA molecule which was the most bent was the one with the 18-bp spacer, suggesting that the 18-bp spacer places the two 140° IHF-induced bends on the same face of the double helix. The spacer arm length (11.4 angstroms) is the final maximum molecular distance between conjugated molecules (i.e., nitrogens of the target amines). adj., adj spa´tial.
