Related to Transposable element: Jumping genes


A segment of DNA that is capable of moving into a new position within the same or another chromosome or plasmid. Also called jumping gene.


(Genetics) genetics a genetic element that can move from one site in a chromosome to another site in the same or a different chromosome and thus alter the genetic constitution of the organism
[C20: from transpos(e) + -on]


(trænsˈpoʊ zɒn)

a gene or set of genes capable of inserting copies of itself into other DNA sites within the same cell. Also called jumping gene.
