Adjective
insertional (not comparable)
That involves insertion.
Sometimes the insertion of a TE into a gene can disrupt that gene's function in a reversible manner, in a process called insertional mutagenesis ; transposase-mediated excision of the DNA transposon restores gene function. Source: Internet
This gives rise to a concern that insertional mutagenesis due to integration into the host genome might lead to cancer or leukemia. Source: Internet
