Question 4

Suppose a scientist wants to identify a gene in a particular plant species by transposon tagging, but he is initially stumped because he finds no active transposons. He hypothesizes, however, that he can introduce a transposon from another plant species. Why might this be possible?

Accepted Answer

transgenes
