lac operon

Post by klapausius » Tue May 04, 2010 4:44 pm

Under normal onditions in wild-type e.coli, the lac operon is under _______control.
a) positive
b) negative
c) inducible
d) both b and c
e) all of the above

my answer b) negative
although it is inducible, "inducible is not a control" < is this statement correct?
or should the answer be d) ?

i would say go with d
though it isn't necessarily termed "inducible conrol", it is inducible (as you know)
if this is a test, it's testing what you know, and it probably wants to see that

I'm not sure, but if is it inducible, isn't that positive control?

Cis or trans? That's what matters.
