Abstract excerpt
A significant proportion of the genomes of higher plants and vertebrates consists of transposable elements and their derivatives. Autonomous DNA type transposons encode a transposase that enables them to mobilize to a new chromosomal position in the host genome by a cut-and-paste mechanism. As this is potentially mutagenic, the host limits transposition through epigenetic gene silencing and heterochromatin...
