mutant (FM13) deficient in phenazine production were obtained following transposon
mutagenesis of PNA1 (Schnider et a1.,1995).
Unlike piggyBac or other transposons
, the JcDNV vector enters only the somatic, or body, cells--not the germline, or reproductive, cells--so the next generation will not inherit the genes.

These promoterless genes lie near one end of a modified Tn5 transposon
which also encodes kanamycin resistance ([Km.sup.r]).
Sometime long in the past, Zapotec farmers must have selected kernels for reseeding that contained an inhibitor of the mutator transposon
, whose effect is thus countered as long as the maize is exclusively inbred, If crossed with other races, however, the mutator transposon
can escape to other breeds and act like a genetic time bomb.
Sex pili are formed that enable direct contact between cells and an 11-kb transposon
TN1546 subsequently is transferred, inducing resistance to the susceptible bacterium.
Mutation in the existing DNA or acquisition of foreign DNA results in acquired resistance.8 For high-level aminoglycoside resistance (MIC >2000 ug /mL), either ribosomal mutation is acquired or aminoglycoside-modifying enzyme is acquired via plasmid.12 Resistance to chloramphenicol is either enzymatic or plasmid-borne and resistance to high-level erythromycin is the result of transposon
encoding macrolide resistance.13 Resistance to glycopeptides can be plasmid-borne or chromosomal and is due to a cluster of genes absent in normal enterococci.14 The MICs used for enterococcal treatment have been identified (Table).

Tdrd5 is essential for transposon
silencing and spermiogenesis in the mice (Yabuta et al., 2011).
The acquisition brings to Immusoft renowned scientific expertise and key technology, the Sleeping Beauty Transposon
System, which Discovery Genomics uses to deliver genes into cells without using a virus.
Karma in palm oil plants is a "jumping gene," or transposon
, a selfish bit of DNA that copies and inserts itself in a host's DNA.
