transposase is either partially or com-
pletely deleted. Typically, the number of
nonautonomous copies representing a par-
ticular hAT family is at least an order of
magnitude higher than the copy number of
the corresponding autonomous elements.
Sometimes,
nonautonomous
elements
differ from their autonomous compan-
ions by possessing additional internal
fragments (for example, MER5A-B and
Charlie10
). It is possible that these addi-
tional fragments represent genomic DNA
