A type of mutation in which a new DNA base is inserted into an existing sequence of DNA bases. This shifts the reference frame in protein synthesis, resulting (sometimes) in altered amino acid sequences.
A type of translocation in which an interstitial segment from one chromosome (resulting from two breaks) is inserted within a nonhomologous chromosome at a third breakpoint. A transgene insertion involves genetic material derived from another organism, introduced by pronuclear microinjection of DNA or incorporation of exogenous DNA by embryonic stem cells (either by viral infection or electroporation), and incorporated into a host chromosome at a random or targeted location.
The addition of a piece of chromosomal material into a chromosome in a place where it is not normally found. This may result in a disorder, because the genetic code may then be read or translated incorrectly.

That which is set in or inserted, such as a word or passage in a composition, or a narrow strip of embroidered lace, muslin, or cambric; as, there were numerous insertions and corrections to the first draft.
