Transposon InsertionsTransposon Insertions
From Ursula Goodenough:
This is largely irrelevant to your question, but we've found 3
mutations in the sexual-fusion gene that are caused by Tcr1 (1x) and
Tcr3 (2x). In two cases the strains were exposed to uv before the
screen (whether the insertions were in fact elicited by the uv or
preexisted in the culture is of course unknown) and the third was
"spontaneous". So, these things definitely happen.
From David Stern:
we had collected a few transposon probes on a couple of occasions
when we thought things might be due to transpositions. although
there are often polymorphisms none has ever segregated faithfully
with a mutation. but the sample size is only two...
Thanks again to those who replied.
