Transposons: Mobile DNA DNA
... DNA transposons are able to transpose in direct, DNA-DNA manner and are present in prokaryotes and eukaryotes Two distinct mechanisms of transposition: •Replicative transposition – direct interaction between the donor transposon and the target site, resulting in copying of the donor ...
