Figure 3.19.
Illustration of IS transposition and its effects.
a)
An event of IS
transposition with the transposon shown in bold. Note that a sequence with three
elements is deleted at the end of the head of the target gene. Note also that, in this
case, the transposon ends up duplicated in the daughter chromosome.
b)
The sub-
ETs encoded in the mother chromosome (before IS transposition).
c)
The sub-ETs
encoded in the daughter chromosome (after IS transposition) (the transposon
nodes are shown in gray). Note that this insertion changed considerably sub-ET
1
,
creating a new sub-ET two nodes smaller than its mother. Note also that the
transposon “cab” was in a noncoding region before becoming activated.
