| spacer DNA | <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. (18 Nov 1997) |

| untranscribed spacer | <molecular biology> In a DNA strand, a spacer sequence that lies between two coding genes. Spacer sequences are not transcribed by RNA polymerase. (09 Oct 1997) |

| spacer DNA |
Regions of non-transcribed DNA between transcribed repeated genes such as ribosomal RNA genes in eukaryotes. Its function is probably to do with ensuring the high rates of transcription associated with these genes.

| spacer |
a chamber that is used with a metered dose inhaler to help the medication get into the airways better. Spacers also make metered dose inhalers easier to use; spacers are sometimes called "holding chambers."

| spacer |
Anything that takes up space. On a slot car, it could be used on the axle, or on the motor, it could be used on the armature shaft. Made from aluminum, brass, bronze, copper, steel, plastic and phenolic.

| spacer |
A device usually consisting of a plastic chamber that attaches to a metered dose inhaler on one end, with a mouthpiece on the other end. A spacer is intended to help medicine from a metered dose inhaler get into the lungs. Without a spacer, much of the medicine in an inhaler "puff" gets deposited on the tongue or in the back of the throat.
