piggybac造句

• Other researchers subsequently identified three more _ mariner, Minos and piggyBac.
• The TTAA-specific transposon piggyBac is rapidly becoming a highly useful transposon for genetic engineering of a wide variety of species, particularly insects.
• The powerful activity of the PiggyBac transposon system enables genes of interest between the two ITRs in the PB vector to be easily mobilized into target genomes.
• The "'PiggyBac ( PB ) transposon "'is a mobile genetic element that efficiently transposes between vectors and chromosomes via a " cut and paste " mechanism.
• Evidence is accumulating that suggests a superfamily of TTAA-specific mobile elements exists in a diversity of organisms, and that piggyBac-related sequences may be present in a diversity of species.
• Several different mobile host DNA insertions have been identified within the few-polyhedra ( FP ) locus of the baculoviruses AcMNPV and GmMNPV . The insertions most extensively studied are those now designated as tagalong ( formerly TFP3 ) and piggyBac ( formerly IFP2 ).
• More recently, analysis of sequences obtained from the human genome has revealed what appear to be 100 to 500 copies of a fossil element called LOOPER, which has sequence homology to piggyBac, terminates in 5'CCY . . . . GGG 3', and apparently targets TTAA insertion sites.
• Both of these elements are part of a larger family of TTAA-target site specific insertion elements that includes the T . ni derived piggyBac and tagalong elements, the Spodoptera frugiperda derived elements IFP1.6 and 290 bp insertion of Carstens, and the transposon-like insertion within the EcoRI-J, N region of Autographa californica nuclear polyhedrosis virus, whose origin is undefined.
