Describe the difference between DNA transposons and retrotransposons.

In enhancer trapping experiments, a minimal promoter and a reporter gene are placed adjacent to the end of a transposon so that genomic enhancers adjacent to the insertion site can act to drive expression of the reporter gene. In a modification of this approach, a series of enhancers and a promoter can be placed at the end of a transposon so that transcription is activated from the transposon into adjacent genomic DNA. What types of mutations do you expect to be induced by such a transposon in a mutagenesis experiment?

How are flanking direct repeat sequences created by transposition?

In Barbara McClintock's study of corn, which of the following kernel phenotypes did she find was due to transposable elements?

A non-autonomous element is a chromosomal element that can what?
