The trp operon can be induced by the addition of indole propionic acid (IPA), which binds to the trp repressor but does not allow the change in conformation. Upon the addition of IPA, what will be the order of the translation of the enzymes encoded by the operon ?
1
TrpA, TrpB, TrpC, TrpD, TrpE
2
TrpE, TrpD, TrpC, TrpB, TrpA
3
Only TrpE will be translated
4
Only TrpA will be translated
