insertional

pertaining to
1. surgical or reproductive manipulation
2. molecular biological manipulation.

insertional activity
the electrical tracing produced in electromyography as a result of the insertion of the needle electrode.
insertional inactivation
in recombinant DNA technology, an early method for selecting ampicillin (amp+) and tetracycline (tet+) resistant Escherichia coli transformed with plasmids such as pBR 322; foreign DNA was cloned into the tet gene, thereby disrupting the gene and rendering the cell tet, which enabled selection when cells were plated onto amp and tet plates.
