You are studying three fruit fly mutants that affect the APS gene. All three have been caused by transposon(s) jumping into genes.

a) In mutant 1, the APS mRNA is not expressed. What is the most likely place the transposon jumped into?

b) In mutant 2, the APS protein is smaller than normal. What is the most likely place the transposon jumped into?

c) In mutant 3, the APS protein is larger than normal, and appears to now contain a part of the actin protein. What is the most likely place the transposon jumped into? Please draw a diagram to illustrate your answer.
