| insertion | 1. <anatomy> The place of attachment, as of a muscle to the bone which it moves. 2. <genetics> A rare nonreciprocal translocation involving three breaks in which a segment is removed from one chromosome and then inserted into a broken region of a nonhomologous chromosome. Origin: L. Inserere = to join to (18 Nov 1997) |

| insertion mutation | A mutation caused by the insertion of at least one extra nucleotide basein a DNA sequence. (09 Oct 1997) |
| insertion sequence | Mobile nucleotide sequences that occur naturally in the genomes of bacterial populations. When inserted into bacterial DNA, they inactivate the gene concerned, when they are removed the gene regains its activity. Closely related to transposons and range in size from a few hundred to a few thousand bases, but are usually less than 1500 bases. (18 Nov 1997) |
| insertional inactivation | The inactivation of a gene due to the insertion of exogenous genetic material into that gene. (14 Nov 1997) |
| insertional mutagenesis | Generally, mutagenesis of DNA by the insertion of one or more bases. Specific examples: 1. Oncogenesis by insertion of a retrovirus adjacent to a cellular proto-oncogene. 2. A strategy of mutagenesis with transposons. After a round of transposition, progeny are screened by PCR, with transposon and gene specific primers, for the proximity of the transposon sequence to the gene of interest. As PCR can only produce products up to 1-2 kb, a large fraction of progeny identified as positive by PCR will have a transposon close enough to the gene to inactivate or otherwise alter its pattern of expression.

| insertion sequence |
a small bacterial transposon, approximately 1000 bases long, with a short run of inverted repeated sequences at its termini, it causes duplication of the recipient DNA site into which it inserts, one copy of the recipient DNA flanking it on each side.

| insertion activity |
insertional activity, the electrical activity caused by insertion or movement of a needle electrode; it is prolonged in neuropathies and myopathies and is diminished in some metabolic disorders.

| insertion sequence |
The simplest transposable genetic element found in prokaryotes. It is a mobile segment of DNA that contains genes required for the process of insertion of the DNA segment into a chromosome and for the mobilization of the element to different locations.
